90degree twist ccv valves

hey, bought an xj a few days ago and I need to replace both ccv valves the front is broken and the rear is gummed all to hell. I have found many write ups talking about push in valves that look to just pop into a rubber grommet in a hole in the valvecover. My ccv valves are 90 degree twist type deals and I cant find replacements for them. am I missing something? did the grommet supersede the twist stile? anybody got a part number?

the jeep its self is a 96 but I am now pretty sure sombody swapped the engine at some point to a 92-94 i think. It has a twist lock style oil fill cap and ccv elbows. I called a local jeep dealer and got a good intelligent parts guy on the phone, he knew what I was talking about but couldnt look it up in the computer. I decided I will just go pull a newer valve cover from the local picknpull on my day off and use the newer easier to come by ccv system. On first inspection the jeep looked decent with a few minor odds and ends but now I am not sure how deep I am going to have to go into it.

can anyone tell me what I the major differences are in the early 90s and the 96 4.0s? in other words what else am I going to have trouble tracking down?
