Troy I have the K frame seal, in 80 durometer rubber you'll need to procure the "speedo" lips that hold it in place,.....Patik sells the "original" style one that's very stiff, 100 durometer rubber you may find it hard to conform to the K frame?,........remove the rear cowl seal on the hood, that helps relieve underhood temps,.......the master lines for the wingcars using the inboard style can be a problem,.....I'd suggest a switch to dot4 ATE Blue racing brake fluid, premium fluid found at Porsche dealerships, some parts stores may carry it, $40 a quart about 550-580 boil point
