info on the early 8 3/4 pumpkin

Same unit as the 741, 657 was a superceded part number. It will drop into any 8 3/4" housing!! They did have a couple goofy ratios not currently offered though, I had a 3:31 in my 64 Belvedere. Swapped just the center section into a 65 and later housing and put it back in to eliminate the keywayed drums!! Geof
