thanks to you both!! since money is a little tight, I'm going to have to put off buying another whole tranny, but I do know which one I want now!!!
On another note, I tweaked my TPS and timing at the dizzy, and now I can lean burn at 70 mph! ( still at about 2750 rpm ) check me out - the smiley light is my "econo" light:
If I do find a definitive partnumber for the final drive gear with 3.25, I'll share it here.
Thanks again, all!!
