I have a '71 FJ40 that I swapped in a newer 4speed transfer case. Some drive shafts came with the tcase when I bought it. The tcase and shafts had been mated to chevy axles so the drive shaft flanges at the pinion end won't work on my 40. The shafts are custom made long splines with spicer 1310 ujoints.
I want to mate these up to my '71 pinion flanges with the least amount of work and expense. The early pickups (8/78 - 7/83) have the same bolt pattern of 64mm x 56mm using 8mm bolts. The '71 pinion flanges are also 64 x 56, but use 10mm bolts.
I have found drive shaft flanges for the older pickups that will hold the 1310 ujoints. However, not having ever had a set of early pickup flanges in my hands I don't know if the bolt holes can be drilled out to 10mm, or better yet 11mm and still have enough boss area to stay strong.
Does anyone know if this can be done?
Thanks,
Steve
