I am going to get 90/10 for the front and 50/50 for the back(70 Mav.) What year Mustang will I need to order them for?****************************************************************
Summit offers Pt # SUM-G7603 for the front. Lists 1965-70 Mustang and 1969-77 Maverick. They are 3-way adjustable. I have them on my car along w/ 6 cylinder springs from a 1965 Mustang and the car transfers really well.
As for the back, I do not see a listing. You can call Summit and find out. I just used the cheapo Napa replacement shocks and generic Lakewood traction bars when my car had leaf springs.
The whole combination worked really well. With a naturally aspirated 302, the car would cut consistent 1.56-1.58 60' times (pulling the fron tires about 8" off the ground). Kind of wish I still had the leafs on the back as it made the car easier to drive on the street (although driving around with the ladder bars is not too terribly bad).
