the factory fill plug was on the old cover plate, I put in 3qt I guess im going to call it good, factory capacity is supposedly 2.2~2.41qts and the cover is supposed to add 1/2 pint extra capacity so it has to be pretty dam close???

the factory one does yes, but this ta performance girdle say's 1/2" npt in the manual, I didn't have anything fit, so i went hunting for a 1/2" allen-----NOPE, finally got it off and then took it to the store with me, would have been nice if they would have put in the manual that it takes a 3/8" allen

1/2" npt is the thread size (National Pipe Thread).

Yes, and I have no idea why they put that info in the instructions but not the allen size. Like we’re going to go buy our own plug to put in there?
Ya, I kinda figured it would take a 1/2" Allen, but o"well I got it done and have a nice new set of Craftsmen sae Allen wrenches now, lol
I was just missing the 3/8's, the hardest part was beating the panhard bar on it fought me all way, took 2 sets of rubber mallets because there is no room under the truck to swing so I did it from outside the driver's wheel well, I put one mallet on the bar then smacked it with the other mallet

If you need a 1/2” Allen why not just a 1/2” drive ratchet wrench?
would get the same results

I’m thinking that the hex drive won’t work with the square drive on a ratchet handle.
I tried everything I had at my disposal, I did finally get it off by wedging a flat head in with a smaller allen, I didn't want to put it back in like that and damage it though.If you need a 1/2” Allen why not just a 1/2” drive ratchet wrench?
