u joints thats all you should need is a different u joint. they come in many sizes. measure the cups and widths. give them to your parts guy or uhmm gal. napa will have them. i cant remeber the part number so im no help there. but just measure cup diameter for both drive shaft and 9 inch yolk, then the width of both then you should be good to go
have your parts person pull a u-joint for a 9" 57 ford and one for a '75 maverick 8". measure the 9" on one side and the 8" on one side. tell them you need one with thoes measurments...then adjust from there if needed... ......
Everyone has hinted at it, but what needs a little clarification here is that you need to ask for a special u-joint that is made for a non-stock application. These are made for this kind of swap. A stock u-joint usually is the same size in both dimensions. What you need has both sizes built into it.
