Mike, I just bought a Macgregor 22 also, but an '85. I am working now on the trailer and would like to see some pictures of it if possible. I think one of the previous owners did some modifications and I would like to compare mine with yours. I am mostly interested in the bunks. How long are they? Normal 8' 2x6? From what I can see through the grass, you may have a similar problem. The boat sits against the wheel well and rubs. I can send you pictures if you send me your e-mail (I haven't posted 5 times yet and they won't let you post pictures until you have posted 5 times). jchalk at rgv dot rr dot com
I'll snap a couple of pics within the next few days. But I can tell you that mine isn't riding on the wheel wells at all.
