I am so proud of myself. I got a like brand new camoplast track with 192 pro installed studs for 300 bucks. its like you installed it , drove it 40 miles and took it off. Anyway... the lugs measure 22 mm and the studs measure 32 mm. even with tall tunnel protectors is that too much ?

22mm = .8661= 3/4 lug 32mm= 1.260 = 1 1/4 stud sounds like a good radar run track. dont know the bulkhead clearence on a 96 z but anyways thats what your dealing with

the lug seams to be closer to 7/8 and the stud 1 3/8

1-1/4 stud is Max length for a F-chassis, and then you have to run the track tight so it doesn't balloon too much. You would have to drop & roll the chaincase or use 8-tooth drivers to run 1-3/8 studs.

where would i buy 8-tooth drivers, I looked on royal last night with no luck.

You can purchase them here:

Here is the part # for 8T extroverts/anti-ratchets: 02-577

If you want to stick with involutes you will need to purchase [(2)half-tooths and (2)full-tooths] Part #'s 02-508, 02-510

Note: They only show the involutes in a 1-1/16" - 1-1/8 shaft but you can usually get them onto a 1-1/4 shaft like you have. Might want to ask Wahl Bros. to be absolutley sure...

*I might still have a slightly used set of 8-tooth extroverts around somewhere, I'll take a look...

very helpfull, thanks . can you use the extroverts by themselves or do have to have the involutes with them?

You only need 2 extroverts.

I knew that was a dumb question after i thought about it for a second
