90 YJ fuel filler neck

Hi all!
Long time lurker first post....I finally rescued a YJ from a life of farm use/abuse and have decided to restore it. My old man bought it new in 1990 but the last couple years between hard use and rust it needed some attention....so the chassis is on one side of the garage and the tub on the other...getting ready to replace some frame sections...I have no idea how the shackles haven't kicked off the frame as there is no bottom to the frame below the rear most shackle. I thinking its because the shock towers rotted off years ago and just the weight of the tub and fuel tank kept them in place. LOL....good news is the tub is in great shape and everything is pretty much stock and she fired right up with a new battery. Can't kill a carbed Inline 6

Rebuilding the fuel tank while it's off trying to round up some parts anyone know the difference between a 90 and 91 fuel filler neck? Is it just the fuel cap? I can find 91s cannot find 90. It's a 20 gallon tank.
Thanks in advance!

I think those are the cutoff years. 90 and down had the metal prong style
91 and newer has the plastic screw on type. I think they fit the same, just need the matching cap.

Thanks! The 90 I have and the pics of the 91 I can find look the same.
