Modified Schumacher Headers for 4-Speed

I had CPPA's 2 inch underchassis headers (the predecessor to TTIs) with my 440 before I changed to these Schumachers. I altered the z bar by having a drop in the z bar using a 1inch square tubing and then had the an "L" piece of steel that went through the header tubes. It was very tight, but it worked for nearly 20 years.
