A set of 5-lug GM 15" x 6" 4-nub steelies
For the front:
CPP 6370SWBK-5OE-S Drum to Disc Swap Kit (which includes)
- Classic Performance Products Stock Height Spindles
- Twelve-inch Standard Vented Rotors (5-lug)
- Calipers
- Dust Shields
- Bearings, Seals and Spindle Nuts
- Dust Caps and Banjo Bolts
- Standard Brake Hoses
A restored Delco-Moraine brake booster (with brackets and push rod)
For the back:
5-lug conversion axles
(need to get)
5-lug brake drum
new shoes
new wheel cylinders L & R
wheel studs (Dorman 610-298.1 - 1/2 x 20)?
I am trying to find a disc/drum prop valve that looks stock. I found one at inlinetube but the price is two-three times the cost of the style that looks like a block of brass. Also, what master cylinder should I get for a factory look considering I will be running a brake booster? I'd really like to source stuff locally if possible so I can get this wrapped up before the first of the year.
I have also read mention of a rubber boot that will be necessary since I am adding the booster to a non-booster truck. Is that correct?
What about my brake "idiot" light on the dash, will that still work once everything is hooked up?
I have also heard about the pinion shaft bolt breaking when doing a axle swap. Does anyone have the part number for a replacement? I can't seem to find that info online. I have the stock (wide) 1970 rear end.
Are there other parts I'm forgetting?
Here are the different prop valves. I'm looking for the factory cast iron style as shown in the first picture but $199 before shipping seems a bit steep.

Are your 15 x 6 Steelies made to clear disk brake rotors?
