Reply to "Header Swap FAQ"

I crawl on top of the ZF all the time...I can't see that my/your body weight would harm the transaxle. I've seen the ZF transaxle used as the actual load bearing member in a friends late 60's early 70's vintage Can Am car chassis. McLaren was the first to start doing it where they actually removed the chassis members that ran to the back of the transaxle to support the transaxle. They hung the suspension off the transaxle and eliminated all supports using the engine/transaxle combo to support the rear of the car. The ZF was not the box of choice for most McLarens...it was the Hewland LG 600 because it would handle 800 horsepower with no problems. But there were a few cars that swapped in a ZF because it was a fully sychro'd box and easier to drive. Your weight shouldn't hurt the box.
