Welcome to the forums, Mike
I live in Beachwood, having grown up in Bayville. There is a small company on my route (I am a UPS driver) called The Jeepsterman who specializes in older Jeeps. The company is owned by a man in his 80's who is a bit, uh, cranky at times (that is a big understatement
) but he knows his stuff about Jeeps and has chicken coops filled with old Jeep parts. His daughter is very nice to deal with and from what I see basically runs the company. They deal in used and new parts. They are also an Omix-Ada dealer.

Good luck with you and your son's restoration project!
