Yes I think it’s a 1992 ford Bronco wiper arm that has a J-hook end that will just pop right on the factory spindles. I did the same to mine and I am also running 18’’ blades.
1994-1996 iirc
The early 90s had a pin arm like the late squares
Just as a side note for anyone doing this swap, the Ford arms are a more round hole vs the oblong of the original GM arm. I was a little concerned at first when I just test fit them without putting them all the way on cuz they seemed loose, but the measurement difference was miniscule and once locked in, they're nice and solid.

A little bit of loctite (yes , seriouslly) is wise if you want to prevent stripping the post
It can be removed if you use a miniscule amount of heat, just use a leather glove or something to lay on the area around it to prevent burning anything
I have an OBS ford arm that has a bit of aluminum stripped from the truck in the splines and extra GM wipers. The angle is not correct for the wipe, but try using wipers at highway speeds if you have a satisfactory wipe you should be fine.
If you look at the wiper when parked and the blade is angled up or down and not square to the glass, it probably will not perform well in heavier rain , as the blade will drag over water rather than push/scrape it
But if you clean windshield perfect and use Rainx that may be something you can mitigate with just keeping it clean
Iirc the wiper arm is a little long so you may not be getting the best place on the driver wiper, but i could be wrong
