Richie: Have you any pics you can post? I used to play with those "ponies" and wonder if the taller/larger tank from a 71-73 would fit. How much room was above the tank you installed? Oh and before I get too far...Thanks for the info. I had not have concidered using foreign parts grin grin

Use a big enough catapult and even pigs can fly...remember nothing is impossible, impractical yes, but never impossible.
