Hi Guys! Several years ago I bought what I was told was a 74 Nova front clip and welded to the front of my 48 3100 P/U. I started rebuilding the suspension this week, however, a bushing set for 74 Nova'* is a no-go. To small. Seems the lower front is 1-5/8"(O.D), and the rear is just under 2" (1.97 O.D.). Can anyone tell me what years/models used this combo? Thanks
