Next-
the week long search for wheel studs... wow, I can negotiate that Dorman site fast now! The web site wouldn't give every dimension I needed so I would get 2 or 3 of the dimensions I needed and then order in the wheel stud and the other "must-have" dimensions wouldn't work for my application... what a hassle! I'd order in about 4-5 different ones every day or two ...
-the key here was to make sure the stud pressed into the hub, not the rotor (can't be sloppy tho)
-that it pressed in far enough and with enough tolerance so the stud wouldn't ever twist when taking lug nut off
- the knurled part of the stud would be on the shank in the position where it would press into the hub... (sounds easy)!!
- long enough totals thread length
- correct diameter...this doesn't seem like a big deal but the early D60 Hi Pinion Snowfighter model from '78-79 run 1/2" wheel studs so I needed them to match front and rear.
- not a reduced shank immediately after the knurling (this was the problem on many "first glance this should fit wheel studs")
I found one, and only 1 that would work to what I felt was needed. I drilled the hubs out to 39/64" (will double check) to make sure the stud pressed in. I really didn't want to have to do any drilling or having to run a taper thru any part just so it would be more OTC but heck, if I'm needing to buy a new wheel hub, it won't be 30 extra minutes to run a drill bit thru the holes so I can press or pound the studs in.
I'll post Dormann part #'s for front D60 and rear 14 bolt Chev ...
