The new part # for part "B" is 10252375 im supposed to have one in at the dealer this tues but if you can modify the existing ones then thats what i will do also, its only $22 but after looking at it today I knew it could be done and hearing from those of you who have just modified the ones already there has inspired me to save $22 also did anybody have problems with the tranny mount itself being too thick, this is my dilemma...mines already to go now besides taking my drive shaft down a few inches, so i dunno if i need to find a shallower mount or what the rubber is about 2" thick and looks nothing like the one shown on the b/m instruction manual, in fact the one that was on the th350 looks alot like the one that was on my 700r4 same thickness anyhow so can i torque down the cross member and old mount with confidence????
