I have a BF on WA who's been into 442s since HS and his garage is full of them. Mainly 64s thru 67. But I'm sure he has a 68, a 69, and a 70 W-30 also. Most of his cars are "keepers," but like all collectors, they'll come across others they pickup to sell now and then. At one point, maybe 20 years ago, he pickup a supper clean 70 Cutless, that was a triple green. It was kind of a lime green on the outside, with a darker green viynal roof. It too might have had a straight 6, and if I recall was a post with a bench seat.
Please keep in mind that anytime I share or give advice about a motorcycle, unless I state otherwise, I am always referring to GL1800's and no other.
