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.
