5 Speed Gear ratio advice?

Remember I was dealing with Keisler's "perfect fit",,you'd be talking to Silver Sport. They bought Keisler but did they do more engineering for their "perfect fit"? Having gone thru it I still dont see how anyone can call it a "perfect fit". That pic you posted of the cross member in the tunnel,,I'd ask them "Is the a pic of an A Body, or a B,E,C,F. We A Boys have the smallest real estate to work with I think. Can't see a non A833 based box fitting in there easily and your looking at the TKO which in my eyes is bigger on to top side.

This is true, I knew they had bought keisler but didn't know the actual transmissions were that much different. Hopefully they did do more engineering than keisler did for the perfect fit kit. The picture I posted comes from their flyer for the A body A41 automatic swap cross member instructions, though the salesman says its the same mod necessary for the 5 speed.
