" My eventual plans for " this car are six pack 280 with a T5, so you're looking for another bell with the sr4/t4/t5 pattern? planning on a mustang 5.0 t5? as i see it, you have two bolt-together options: sr4/t4/t5 bell with gm t5 retainer on the ford tranny late multipattern bell used with t150 or jeep t176/177/178 the amc sr4/t4/t5 all have ford cases but gm-size 4.64" retainers. the t150 and t176 series, in the ford toploader family, have 4.85" retainers, as does the 5.0 t5. if the multipattern bell is actually drilled and tapped with the t5 pattern as well as the t150 one, this would be the easiest approach. iirc the ford t5 should also be just about the same length as a t150, as well as having the same splines in and out, so a grem/spirit t150 driveshaft and yoke is another bolt-up part. if the mustang shifter is too far back in your car, a gm s10 t5 extension case and relevant internal linkage bits is your answer. if you go this far, i'd also suggest the 5speeds.com cluster stabilizer and the aftermarket 0.8:1 5th, while you have the tranny apart. ________________________________________________________________________ Andrew Hay the genius nature internet rambler is to see what all have seen adh@xxxxxxxxxxxxxxxxx and think what none thought
