The Procar seats are nice as far as mounting to a stock type track ,and for a street car,but you're giving away a lot of weight ,they are around 30 # compared to a Kirkey aluminum seat at around 17#.
The Kirkey also is much sturdier, no reclining back to fold in a crash situation.
As far as mounting , the seat back must be attached to the roll cage shoulder bar,and securely attached to the floor.....I always eliminate the seat tracks, they have no strength.
I just used a set of Kirkey's in a 69 Camaro Stocker that saved nearly 60# over the stock seats.
