I bought a 79 Z50 last week for $50. I bumped into a guy at Advance Auto and he asked me if I was interested and I bought it sight unseen on the spot. It's just as he described running but rough. The only thing that keeps it from being ridable is the rear wheel is rusted out and letting the tire hit the swing arm. I'm not sure what models with inter change with the 79. I figured that since these things had been around forever the parts would be dirt cheap, not the case it seems. And snce body parts for the Z's are high I've decided to buy used a CRF50 body. It looks a little different but nothing that should be a problem to make it work. I'm wondering if the CRF wheels will fit the Z? Any info would help or a link to the type of info I need would be great. I'm not a big forum user, so info that I didn't have to join a forum would be a plus.
