Any of you guys lowered a 82 3/4 ton truck and if so what spindles did you use?
The CPP CP4s4 ones I have now don't match up with the brake caliper mounting. Previous owner said he put 82 3/4 ton spindles but the casting numbers 15649948RH and 15649947LH seem to go to 99-2002 and 88-98 in a couple of searches. So this is where I am lost. Hate to keep buying and returning parts.

The calipers on it now mounting bolts to spindle are about 6 inches apart and new spindle and 73 calipers are 7 inches apart if that helps to make clearer
It is a 69 GMC with newer spindles setup ????? year on it.
Thanks
