Thanks guys, I really appreciate your opinions (when I try to ask friends, they don't put to much effort into these type of considerations).
And Bob - at least I think she's a L. I have no history on her, only that first registration year was -67 (and that she's a US import) and that she's got some of the extras that the L had.
Right now I'm thinking about using the rack for ski/snowboard - later maybe for other transportation.
This rear rack, was it original accessories at the time? And did they sell roof rack as well?
