The GOMOG article is written by Mike Miles (A Professional Engineer) who lives in Portland, Oregon. I know Mike and I have re-read the article in GOMOG. Mike is right on. Mike has a lot of experience regarding the drive train of the TR powered +4's. Be sure to thank Lorne Goldman for including Mikes article in "GOMOG".
