73 challenger 340 727. Last year, put a B body 8-34 housing from ,I think a Belvedere, used my old 489 chunk. Could barely get the shaft in , maybe 1/2 left before trans out shaft hit slipyolk end plug. Had a vibration at 60+ mph and solved with 4* shims under the perch, nose up.Then my clearance was all but gone, but it drove well. Just did a 4spd conversion from Brewers. Now it wont install untill I take the axle loose & take the shims out. Anyone else been this route?..What would be suspect 1st? (there will be a test on this later)
