I bought mine for about $100, and then changed over to the Weber. Save the money for your Weber. It would be pretty difficult to adapt it over, the shape isn't conducive to it. Also on the factory kit, you need to specify if you have power brakes or not (PB denotes the teardrop you were talking about).
I've got one that came with my '87 yj.It was just thrown in the back.I'm not sure what is supposed to be there.There is the bottom piece with some vacuum hoses and damper in the intake, and the lid.I can look at it closer if you want.I have a 258 with Carter bbd.Put aftermarket air cleaner on.Would rather trade than sell if you want.
I have the air cleaner on the floor of my garage that was off my '84 CJ with the 258 and the BBD carter. If anyone wants it just email me at [email protected] Make me an offer. I dont have the rectangular hose that attaches to the end and goes to the air box in the fenderwell.
