converting drum to dics info? help?

I am going to attempt to convert my 68 GTO CONV. to disc brakes.

looking to see if there is another A-body car I can use to achieve this instead of buying a kit.

there is lots of salvage yards in the area where I live, so why not use them.

what im looking for is a simple way to take brake parts off a car that will bolt up on my 68. Is there any vehicle out there that is a basic unbolt, bolt on car?

or do i have to mixmatch parts to accomplish this?

has anyone done a salvage yard conversion?


thanks for the help, i know that this topic has most likely been discussed on here before but im not good with searching forums ha. thanks again.

You can do it junkyard style and you have to get the spindles and add a booster to your master.

Here is a thread that answers some of your questions.
Also if you have 14" rims you have to make sure they are compatible.
I have 15" Rally IIs and just bought the conversion kit from Summit, all new stuff including the spindles and master I didn't want to waste a bunch of time screwing around at Pick A Part getting parts and rebuilding them.

We just did a front disc/dual master cyl conversion on a 64. We ended up purchasing a kit from a reputable co.. ( after trying to mix/match new parts that supposedly would work)Even then we had some customizing to do, on a supposed bolt on appl. . It was no surprise or problem, ( just time) my point is=time vs headache vs $. you may want to ponder. Good luck w/ conv. My customer really like shis.

who has the best bang for your buck when it comes down to a new bolt on system? also when you get a system does it come with everything you need? or is there the "things they dont tell you, you need"?

Mine came with everything and took about 6 hrs. to do.
There are different kits and some won't fit 14" wheels but there is a kit for them also.
You will need a kit that has the spindles, you can get stock, drop etc.
I went with stock.

Mine is a '67 and this is the kit I bought.
Minimum wheel diameter is 15" on this one.

Here is the other one for 14" wheels.

You really don't need the discs on the back since most of the stopping power is in the front.
Both of these kits will fit your '68.

Look at the kits, they have a booster and master included you just need to pull vacuum from the manifold and you have power brakes.

My car came from the factory with PB so I already had the vacuum hose.
