Straps and bolts for TH400 1350 coupling
« on: October 08, 2019, 03:36:10 PM »
Just completed swapping in a TH400 tranny in my 76 C10, got to the point of connecting the prop shaft to the output yoke on the gearbox and I have the wrong straps and bolts I got Dana Spicer 3-70-28X which are for the 1350 size u/j but my tranny has the deep pocket yoke so the strap is shallower and the bolt centres are different and uses longer bolts.
Does anyone have the Dana Spicer number for the correct straps and bolts so I can source some locally?
It's now the only thing stopping me being able to move the beast under power.  :(
Thanks
Graham

Further to my last I think I need a Neapco No. 1-0020 or equivalent which matches my yokes exactly?

Cant help you with the numbers but when I worked at AutoZone years ago we would have some straps sitting on the shelf behind the parts counter
