I tried posting pics with my original post and just tried again.  The pics I have are jpeg images and they are all around 120KB.  According to what the site says, I assume the pics would work, but I haven't been able to make them work.  I've also been leaving really early and getting home late with work, so haven't been able to look at the quad again.  I looked at the pictures I have closely though, and the upper front A arms are definitely round tube.  I didn't count the head studs, but the guy I bought it from said it was a seven stud head.  So with round upper A arms and a 7 stud head, it must be an 88-90.  I would like to post some pics if somebody can tell me what I'm doing wrong.  Thanks for the info.

Update:  Just tried posting pics again, this time with small images that were about 45KB total and jpg images.  Still didn't work.  It keeps giving me a message saying the "upload folder is full, contact system admin."  Not sure what that means or how to fix it.  Thanks for any help.
