Ok I am at a cross road where the car will be different on the route I take.

So I have the whole chasis pulled apart and this thing had more grease and dirt on it than I thought. I got it clean enough to see that the entire hardware of the front and rear braking systems was shot. The backing plates were so pitted and rusted. So the rear end builder held off on inserting the axles until I found the backing plates. So when I priced the rear brake system out it was so close to just getting a whole kit pre assembled. So I dropped 430 dollars on a complete set of drum brakes. Those should be here tomorrow. Now the front......

So they are just as bad. The spindle and arm are the only thing useable. So I tried to find a backing plate.... I can't. I can find used ones, but nothing new. Then the drums, springs, shoes, bearings, studs, .... I will be into it for another 400. Then I caught my self.... I could have got a complete system with brake lines for 900. And it would actually stop the car...

I can't do anything about the rears. They will be here soon. But the fronts I think I am just going to go with a disk brake conversion.

It will make this thing easier to drive. But I feel terrible about doing it.

You will appreciate the disc brakes up front the first time you have to do a panic stop because some idiot doesn't know how to drive. So, it really does not hurt value per say and what good is trying to stay original if some day the braking just isn't responsive enough and you crash or total out the car?

Just make sure you get the matching dual reservoir master cylinder and related parts for the disc/drum conversion.

Got a complete rear end rebuild drum brake kit. (430 Dollars) This came with everything need to overhaul the system, Will install it tonight. then it is just 2 bushings on top of the differential and the rear end is DONE. He has not told me final cost on rear end rebuild but hopefully it will be right around 600...
New rear coil spings (70 Dollars) and there is a difference for convert and coup. Those rubber bushings that go onto of the springs were like 30 Dollars for the pair on the rear and equally expensive for the fronts.
Got new 250LBS to 300LBS springs for the front. (120 Dollars)
New upper and lower A Arms (500 dollars)
Rebuilt Transmission (1250 Dollars) This dude though I was crazy rebuilding a 2 speed ST300 Transmission. And to boot he seems to have lost the torque converter and I can not find another one.
Sway Bar was sand blasted and just painted.
New Sway bar bushings and stabilizers (30 Dollars)
New Tierods, center link Ideler arm and pitman Arm (300 Dollars)
New Power Steering Gear Box I got so lucky and found one on Craigslist for (200 Dollars) It was New Old Stock....
Front Disk brake conversion with matching Master Cylinder (480 Dollars)
Front and rear shocks (100 Dollars)
Fuel Lines and brake Lines (300 Dollars)

I am missing all sorts of bolts and clips and dont even know what I need yet on this front.

I am kinda of excited to merry up this transmission and engine together. Just have to find this ST300 torque converter. there is one on eBay but I am not entirely sure if it will work for me. Apparently there are differences because Pontiacs are externally balanced. So this Torque converter has external weights and tabs on it.
