Sourcing Power Steering Parts

Looking to add power steering to my '67 GTO. Guy locally has a 70 lemans he is parting out. His lemans also has AC, I do not. Should everything bolt right up? What am I missing? Thanks!

if truly original '70 model V8 LeMans pump & brackets, that is what you want. The '70 factory AC diam two groove wp pulley (a"128" or "130") will actually help cool the engine a little better than the 8" diam non AC pulley & it's mate the smaller diam"846" crank pulley. Either will fit with 11 bolt timing cover, "tall" 11 bolt pump, & the corresponding "842" & ""843" crank pulleys. Don't like the look of the additional "843" single groove AC pulley just sitting there behind the "842" two groove crank pulley, substitute a round 4 hole reinforcement plate behind the "842" crank pulley. In sending out rebuilt PS pump/bracket/pulley changeovers, for non AC cars like yours, will often send two of the reinforcement plates, one to eliminate the supplemental AC pulley, one to go up front, just like stock.

if i remember correctly you will need to get a rag joint that adapts the two different splines from the manual shaft to the power gearbox. Also if you have headers the long rag joint bolt clearance is tight and would knock on the header in tight turn parking situations, just ground them back a bit on the ends.

The '67 GTO has a different firewall configuration than a '68-'72. Also, the front end parts are different. A '67 GTO with manual steering uses a different center link than a '67 with power steering, and the '68-'72 uses a different center link all together. While some components will exchange, a lot won't. As Pinionhead stated, pulleys and pulley depth is critical, especially if you have the stock 8 bolt water pump/timing cover. Later model pulleys on early pumps generally don't line up without a lot of fiddling.

conversion ....

Hi.... alot of good info above .... here is my take on the conversion

about your p/s conversion ..... a few simple questions are needed to start ....

is your motor still the 67 ? this doesnt matter much but ...

with 670 heads ? 71 ish and later dont have the extra bolt hole we need for p/s pump bracket using the 67-70 brackets

and a 67 timing cover ? if so you need the 2 groove 67 lower crank pulley .... 6 bolt mount to the balancer ... the 70 has a 4 bolt mounting

you may consider pulling your balancer and look it over good .. for swelling of the rubber and hairline crack at the key way ....

maybe even replace the seal and look at the rub mark on the balancer for seal wear .... is the seal weeping now ?

these tend to have problems .....

how is your cooling on hot days last summer ?? if ok we would look for correct non ac pulleys.... but as OLE Pinion head mentioned above

the ac pulleys are harder to find but cool a bit better .... larger diameter crank .. smaller w pump pulley larger P/S pulley

we just hung a 69 power steering box on a 66 no issues with manual steer originally

buy everything off the front of the motor ... pump .... hoses ... steering box ... bolts .... belts etc ,.... the 70 ac pulleys have good value here on line

you should be able to sell them for the money to get the early stuff

you need a small diameter 67 68 ac 2 groove water pump pulley .... 9787909 67 ac or 9788886 68 ac .....

you already will have the ac p/s pulley large diameter from the 70

the crank pulley ac is 9788193 for 67 ..

you will need the 2 upper alternator straps also for the 67 68 for alt adjustment

sell the 70 one to cover cost or use it ... but the are big n uggly like chevy ones .. and you will need to change out intake bolts to mount it.. they have

studs on the top of the bolt to mount the 70 bracket .....

you will need the stud from the front of the thermostat housing tooo if your manual motor doesnt have it for the alt strap to bolt to...

get the steering box WITH the pitman arm ......

buy a new rag joint for saftey and tight steering ... but get his off the column ,,, you will need 12 point socket 7/16 I think its a 12 point bolt to remove

I am sure there is more but we can help you thru it

I am sure there is something I forgot or may not be correct .... but thats what we are here to chat about

Some great info guys, thank you. Motor although not #'s matching is a '67 with 670 heads. I already bought a PS box WITH pitman arm and rag joint needed to complete that part of the conversion (hopefully). These part numbers on pulleys and brackets should help immensely. I'm sure I'll be getting back more more questions.

Chad, how many bolts are attaching the crank pulley to the damper, 6 or 4?
At a glance, I can't tell, but the big cup shape design of the rear of the crank pulley leads me to believe you have a '67 2 groove NON AC crank pulley on a '67 & earlier damper (balancer). That style damper & crank pulley can't be used with the 11 bolt timing cover.

The timing cover in the pic, as well as the water pump are the 11 bolt style. These are part of the pieces I've put together in many dozen "11 bolt WP/ PS changeovers". Changeovers which I've been putting together for '65-68 owners since the early 90's. The 11 bolt PS changeover is basically '70 Pontiac V8 model (exc V8 Firebird) pieces. The PS & pulley setup in my changeovers use the strap type alt brackets that were used on very early production '70 models, as well as ALL '69 model V8 Pontiacs with PS. When the setup is put together with the correct pieces, it looks nearly stock, but allows the use of the '68+ damper & 11 bolt "tall" water pump. Both of the latter are very common pieces, & typically avail affordably, as well as with the option for various SFI rated dampers & with quite a few water pump options.

hmmm

looks like a

69 -70 timing cover ...with a 67 n older balancer....

the timing pad is way away from the balancer in the one picture ....

thats looks to be an early balancer with 6 bolt mount ...

its not a 68 cover because it has the 11 bolt water pump ....

you need a later harmonic balancer 68 n newer ... buy a new one ....and a 68 69 70 crank pulley ...

and we still need the numbers off your water pump pulley and power steering pulley

I'll get numbers as soon as the engine comes back from the machine shop.
