I am useing a BB 727 short shaft bolt on yoke in my 88 440 truck..engine is in the sig pic
the u-joint is 4" across with 1 1/4" round caps
measure the tranz mount distance from back of case
I had to move the xmember forward 2" in my truck..after building a xmember out of some square stock and lower brakets
a reg long tail shaft 727 or a reg 4x4 short 727 will have the mount center 7" from back of case
the MH short 727 will be 5" from back of case
think those MH 727 are for a 1 1/4 ton chassis
the speedo hook up is in a diff spot also when trying a stock xmember on it
I went with a full manual Vb to loose the linkage and will use a floor mount lokar shifter
I looked at a gennie shifter..but wont have room on top of tranz and floor pan
the lokar will mount inside cab on the floor and have rod linkage for the hook up
