I order a ZC engine for my 90 HB. It has been more than a month now. The the shop calls me and tells me they don't have any ZCs. I'm pissed, I tell them I want my money back. They tell me they don't have my money they gave it to the importer. They offer a 95 ZC . They say it will fit and it's no big deal. I belived them. Now I'm not so sure, can any of you guys tell me if it will fit? What kinda modifications am I going to have to make?
