That's fine. They are literally sitting in my garage taking up space. They won't solve the braking issue, but they will give you the drop you are looking for and add a nice stance to the Monte. Of you are interested, shoot me an offer @ email@example.com. As long as you are fine with paying the shipping, I won't refuse a reasonable offer.
Expand your search to 73-77 A body and 70-81 F body drop spindles, front suspension is the same as a B body.
Im not well versed on the years but the later B body spindles are made for a slightly larger rotor, and the caliper mount I believe is slightly repositioned to account for it (possibly not even noticeable)
They also made the change on the outer bearing in 79 or 80 like the G body spindles did.
There was also 2 different bolt patterns available for these spindles 5x5 for the later Bs and 5x4.75 for everything else.
