Here's a quick little update, Today with the help of my good friends Knife, File, and Sandpaper the tranny from the front engine was removed and setup to link the engines together. Both engines are from 67 GTX's. I have 2 because when I tried to build one 7 - 8 odd years ago as my second or third build ever I messed it up somehow. I don't really remember but either the paint screwed up or something fell on it. In any case the body was toast. Wal-Mart at the time had all their models clearanced out for like 5-7 bucks so I just got another and that's how I ended up with 2 identical engines.
Anyway that's the story behind the engines now here are some pictures, starting with engine #1
Engine #2
And here they are linked up, I tried my hand at making a flywheel for engine #1 but it didn't turn out to well so I may end up redoing it later on
Thanks for looking!
