How can you check the spindel's

Yeah,... I was kind of surprised too. I was telling him I was holding off on doing the full BBP swap because of the cost of front kit, rear kit, axles, then having to buy new wheels and tires for the big bolt pattern. His reply was:

"You could run my Stage 1 front disc brake kit with a pair of MBM 5 x 4" bolt pattern rotors swapped in."

I then asked if I could just swap out rotors in the future when I am ready to change everything out to BBP, or if I would have to redo the front again. He said:

"If you want to convert to 5 x 4.5" bolt pattern in the future, you can simply install a pair of off-the-shelf '73 and newer A-body rotors."

Unfortunately, the conversion pushes the front wheels out 3/4" (front and rear) and with the backspacing on my my current stock 14" ralleye wheels, it looks like it will be awful close to the fender and I'm afraid it would hit when turning and hitting a bump. Soooo,.... guess I will stash a little money away here and there until I can swing the whole BBP conversion price. I don't mind the rallye wheels, but discs up front would be nice!

Right, the MBM rotors, gotcha. Yeah hopefully they’ve sorted out the production issues with those, there’s been a few people here that have had run out and casting issues with those.

And then there’s the track width change, going to the 73+ brake set up while keeping the SBP. Some wheel/tire combo’s can probably pull that off, but I’m sure not all of them can.

You’ve got 14” rallies, do you know the width and backspace?
