1991 Silverado frame off rebuild-LS powered

[mike205]

The rear end is a 4wd unit from the same body style so it was a direct bolt in, the front is just 2500 light duty rotors (6 instead of 8). I'm using 92+ drop spindles; 88-91 regular cab spindles/rotors are different.

What the differents with the 88-91 spindles
I was wondering I have 89 with drop spindles could I use them?

I want to say the shaft the rotor slides onto is smaller. To ad more confusion it was only the 88-91 regular cabs. Extended cabs and SS trucks prior to 92 used the larger size.

Ok so all I have to do is swap my spindles?
Can I still use everything else like calipers and mounting hardware

You'll need 92+ spindles and im sure rotors. Calipers should still work but I may be wrong, it's a rare occurance but it does happen.

Nope, the calipers are different. The early standard cab rotors were thinner and didnt cool as well. Thats why they went to the thicker rotor in the extra-cab and SS 454. If you are changing to 6-lug anyway, go with the 3/4T calipers too-they have a slightly larger diameter piston, and were made for that rotor.

Ok cool
