I'm looking for the 3 bike side mounts. I have a set for a 80-81 GL1100, and the sidecar pylons. I would like to find a set for an 82-83 GL1100, as well as a GL1200. A machinist friend of mine is interested in making some, if he can do it for a reasonable price.
DMC Sidecar in Washington bought the remaining stock of Terraplane mounts some years back, and when they only sold two or three sets a year, they sent them all to the recycler - what a waste. They now make a custom 4-point mount for the Terraplane which fits their universal motorcycle mount. $750 for the sidecar mount and approx $775 for the motorcycle side. Way too rich for my blood!! I wonder how many sets of those they sell a year? Good luck with your mounts. I'll let you know how my deal turns out.
Just picked this up...lowest vin# I have seen...changed to a four point..no disc brake body in great condition has original seat covers [top and bottom] that could be used as a pattern and the original foam seat...too many projects....any offers???
My machinist "buddy" bowed out on me - had too many better paying jobs. I'm still scouring eBay & craigslist, but not having any luck, so far. I have only the set that came with my Terraplane, which I hope will work on an 82 Interstate I'm trying to bring back to life. I'll post any finds or info I dig up. Sorry I can't help yet. Ray
