Longer wheel studs

[mbrown5]

I've just got around to fitting my 18" RL7s and have found that the studs are too short for the rears. How can this be possible? TVR only fitted one size of studs and there are a few Cerbs about that run or have run 18" RL7s so how can mine not fit? Are all the Cerbs with these wheels on using dangerously short studs on the rear?
Does anybody know what size the rear studs are? I know the hubs are off a Jeep Cherokee but when searching the web for Cherokee studs I can find some with 0.618 inch knurl and some with 0.625 inch knurl. I can find longer studs of both knurl sizes but not sure which knurl size I need? Can anybody help!

There are plenty of old topics/threads on here, just do a search. why not buy from TVR power?
They are cherokee 1/2 UNF. Plenty of options eg ebay, TVR Power, recetech direct.....

Sorry I've not explained very well what I need. I already have standard length studs but I need longer ones. I can find the correct thread size (1/2 UNF) in the length I want but need to know which knurl size Cerbs use. Cherokee studs come in either 0.618 or 0.625 but which one of those two do Cerbs use?
I've done search but can't find this info on the forums.

knock one out and measure it then put it back on

Car is now at X works being serviced so will ask them to measure them for me. Just thought someone on here might have known.

I recall my 18 inch rl's bolts were wrong for replacement spiders. I assumed 17 and18 RLs used the same bolts.

Meant to reply to this before, I fitted some of these which are a few mm longer than the standard studs:

I asked this question last week as spiders have a tapered face and RLs seem to have a flat face. I need ones for my Rls

Really? My RLs have a taper on them, certainly I've never heard of RL7 specific wheel nuts.

100% I looked days ago look at 17" rl7 next to 18" spiders very different faces for the nuts.
