For the benefit of those who can't read our PMs, I'll post the link to the M37 G741 Forum. This is a dedicated M37 Forum and you can get solid technical advice, opinions based on experience and post on the Swap forum for Needs and Wants. This doesn't replace this great forum and Canadian members will want to look in on both MLU and the G741 for local sources and like minded people.
There are several members on G741 who are located just over the border? in Vermont and New York that may have fenders.
