Sorry to hijack your thread, I just called the local part store to get a torque converter and had zero luck, they said the 85 CJ with a 258 never came with a TF999 so they didn't wanna talk to me. What year vehicle came with a 258 and 999 that they would have in their computer? Maybe a scrambler? If anybody knows right off hand that would be great, then I can get a TC and flex plate and skip the sarcastic point of view from the not so helpful guy behind the counter..
'86 CJ7. Probably more, but this one I know!
Also, my TF999 came out of an '88 YJ. Bolted right in to my '86. Got my flexplate and bolts from the local Dodge dealer.
Beer is the answer - it doesn't matter what the question is!
The TF-999 started in the 80 CJ-7 and ran to 86 and was also used 87-90 in YJs. They showed up in some 6cyl FSJs but they are hit or miss. Stick with the 80-86 CJ7 with a 258 for reference. Also, some were lockup and some were not. If the last 5/8" of the input is smooth (no splines) then it needs a lockup converter. If it is splined all the way to the end it is non-lockup. You may need to specify which one to the parts guy. I priced converters for when I am ready to do my rebuild and I found not all places carry them. Make sure you go for a low stall.
