Getting the Wheeling Fever

Just picked up an 83 for real cheap that im going to use for my SAS and stuff my question is I was wondering if a 3rd member out of the 83 would work in my 86 both being 4.10's. I thought I heard the the bolt pattern for the drive shaft flange was drilled differntly??? Is that true or could I pop a 3rd member off the 83 and bolt it right into my 86 rear? Thanks guys Stinson

The 3rd will swap over. The flange is likely drilled different. Eitehr open up the holes to fit the newer (larger) bolts, or double-drill the flange to fit or pick up a replacement flange that fits or swap the flanges as needed.

Correct but the shaft ends may be different as you said. Willl work with cross drilled flanges, as long as you put it in the rear as stated. <img src="/forums/images/graemlins/kewl.gif" alt="" />

Thanks guys one more question, if I were to cross drill/ redrill the flange how do I make sure the the flage is centered/holes drilled in the right spot? Just want to make sure I dont have a vibration problem.

I made a jig to align the flanges:

My original jig was just a piece of wood whittled down to fit. Or slap the driveshaft onto the flange and use it's holes to locate where to drill. No worries about centering since the lip in the center of the shaft fits into the recess in the face of the flange. An alignment jig is only needed when doing a flange-flange drilling.
