You know those little bastages. The little "rivet" that holds the ID tag onto the transmission. I was thinking about how I was going to likely get a good transmission shop to rebuild/restore the transmission in the 85 442. But I also know if that happens, it's going to have to be dunked and cleaned, and...well, the ID tag probably wouldn't hold up. I won't trust any old shop with such a unicorn part like that tag, so I'm figuring I'd have to take it off of there myself before it went to the shop.

Getting a new rivet isn't an issue. But has anyone taken one off? I never have, ironically. I've taken just about every other thing off one of these cars. There's obviously no way to drive it out from the back, so I'm thinking to tape off the plate, take a Dremel cutoff wheel or something like that and grind a slot in the rivet head. Then hopefully take a screwdriver and back it on out, or at least enough to get some vise grips (ok, an adjustable locking plier) on that bad boy and twist it on out of there.

Will I regret this? Or is there a better way? Trying to keep the tag 100% in tact and undamaged.

Ideas please. TIA

Center punch, center drill then EZ out, since you don't want to kill/mar/damage the tag.

I have pulled them out of the bottom of cast iron intakes in the past by getting a good bite with locking pliers and rotating CCW, but that's just a stamped steel shield, so no biggie if it gets scraped.

They USUALLY come out pretty easily once they get started, but LH drillbits are a Godsend, IMO
