Yep, plugs are on the rear half of the case, but ... Tonka ain't bein' parted out ... now, if you had a spare t-case lying around .... say an auto t-case ... <img src="/forums/images/graemlins/pfft.gif" alt="" /> ... I'd still need a fix cause I'd be using that auto t-case for something different ... <img src="/forums/images/graemlins/rolleyes.gif" alt="" />

Has anyone calipered their t-case drain bolt? I have to come clean and admit, my measurements above came from my front diff bolt (Hey they both have a 24mm hex nut on top, they could be the same ???) ... but, I'll be honest, I did that because I really didn't want to drain and place that plug again in case it wouldn't take, so ... maybe ... the t-case drain plug is smaller in diameter than 20mm and a 3/4" self tapper or 3/4" tap and bolt would work?

FWIW I found out today that a 3/4" "pipe-thread" is WAY larger than 3/4". What were those guys smoking when they came up with that??? <img src="/forums/images/graemlins/drunk.gif" alt="" /> [Hey Bob ... see that pipe over there that's about as large as your head ... what say we call that one 3/4" ....]

FWIW (2) I did also find that I can get "over-sized" drain plugs (oil not t-case but similar(?) ), so if I can get an accurate measurement, perhaps I can get one of these ... still have to tap the t-case though cause the threads are gone ....

FWIW (3) the thread pitch on our t-case drain plugs (OK oil drain plugs - but I'm assuming now that they're similar) are 1.50 if anybody cares....

Any other ideas??
