That sounds easy enough. Did you use a drill press? I don't have one, but may be able to use someone else's. I'd hate to have lug studs all crooked
This is all going in the '65 C20 in my avatar. I discovered in my parts truck's HO52, that it housed a 4.11 3rd member. I went to move the sometimes daily driven truck the other day to remove the radiator for it to be cleaned and sealed, when my clutch decided to act up. I have been wanting to swap in my SM420 and Ranger OD, but have been enjoying the current setup in the truck. Well, if I have to remove the transmission to work on the clutch, a trans swap is in order, along with an upgrade to the HO52. I swapped in front disc in November 2015, so the braking is much improved, but now for a few more upgrades, and more modern 13 inch brakes will be a nice addition.
