Thanks for the picture, looks very similar to the '95 roadmaster front steer.
Called Steeroids who make Rack & Pin for c3 corvettes. They said the c3 rack has 6.1" of throw. They gave me Advantage West's number who remanufacture R&P. Advantage West said the Cavalier style was the only center take off unit they have and it has 6.5" of travel. They gave me number for Ron at RPM Engineering who has done many R&P designs for ond Cadillacs. No answer & his amswerin machine is full so maybe he is on vacation. Without a longer travel R&B, GM power steer box for a C3 may be the way to go. Just use a longer arm off the box to increase throw to 7 inches.
1) Does anyone have any tips for making this type of set up as tight as possible?
Thanks
