I agree with all the above posts.
You can use the FWDHardware stock#s to get the correct yoke from your local Spicer dealer.
Warning: The ever so popular 'drill out yer strap style yoke an' get a wider style U bolt to convert' is not so hot!
When you do this it is probably better than straps but IS NO SUBSTITUTION for a proper U bolt style yoke... because the correct yoke's U bolts hug the sides of the U joint's cap were the cheap conversion's U bolt is swagged wider to go into the outboarded pattern of a converted strap mount.
It just ain't the same thang ... and won't hold near as well ...
An that's the truth ... buzzz ...
