drop spindles
 

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

Re: drop spindles
 

didn't you identify these as 88ish a couple of years back? unless you are determined to keep it 6 lug or 3/4 ton I would just go to a salvage yard and get the entire front suspension from a 82 and order the parts to match the correct year and make

Well that is the year range the casting numbers seem to ID to but I would like to try and keep it 5 lug as it is now and keep the brake parts and ball joints already installed. I can't find drop spindles to fit what is on it now. Just trying to save money and time changing all of those parts if I put the CPP 4s4 spindles on it. I guess I will change the whole front back to 73 stuff and go from there.
Thanks
