Suck on the filler hole, did you buy the cover new?
The cover is new, but the filler for the AMC 20 is the hex one on the front side of the axle housing... someone stripped the hell out of it.
I forgot to snap a picture, but I can't get vice grips on it, can't even really get at it with a chisel.
I tried quickly to heat it up and tried to pound in the socket with a hammer, but even a little force spins it inside the hole.
I just didn't notice it when I had the axle out and was putting in the locker or I would have gotten it out then... and it would have been a ton easier.
I was having a beer and looing at the Jeep last night... I am thinking overall the stance is great and fills the wheel wells nicely with the 33x12.5x15s... but 35's might be decent as well.
This frame has a 1" lift built into it with the 2x4 construction... and using 1" Daystart BL pucks, so that with the 2.5 BDS gives 4.5" and anoterh 3/4" on the shackles... so I might have to mock them up... not sure.
I got to get it mounted on the front mount of the radiator, and then the front 2 mounts of the cab so it is all square and nice, then tighten it all down and make sure it is all level so I can mock in the rear most mounts of the cab.
They are currently there, but need to be moved forward with cutting and stretching the frame.
