Manual tranny,and parts for conversion

I did a little checking and it looks like you could just use a 75 to 80 bellhousing, PN 3743859, double check with Brewer's Performance, for the "A" or "F" body A833OD and use 74 duster everything and it should bolt in and go. Try to find one with a 30 spline output shaft, a bit stronger. Are you running a 904 now behind the 318? The only thing else you should need is the 4 speed hump. You can even get them new. Have it welded in after you install the trans and shifter, to center it on the shifter in neutral.
