Re: drop Spindle
I'm guessing you have a truck someone already converted and you want to go from a stock height spindle to a drop spindle? GM did not put disc brakes on trucks until 1971.
If someone already converted it, you *may* already have all the "1971-1972 style" parts on it already. You need to find the part number on the spindle you have now. Every aftermarket and GM spindle I've ever seen has a P/N so it's there somewhere. You can then find out what you actually have. If you're lucky, someone put a 71-72 disc brake system on your truck. Heck, someone could have even put a 1973+ disc brake system under it.
