TIMCHNE,

So you moved the engine forward 1" and left the transmission crossmember in its original position (4 speed?) ? Did you drill new holes in the frame for the engine crossmember or use factory holes?

When you say you modified the tranmission crossmember, did you lower it in anyway? how was the condition of the rubber/poly transmission mount? I wonder if I'm having cab clearance issues because my mounts are new.
