Will 70 granada spindles work on my car

[David Fulford]

My car has an "L" in the VIN number which should mean it had the I6 in it at one time.
It now has a 302 and 5 lug drum brakes all the way around. Being that it is now 5 lug, are the ball joints and tie rod ends going to match right up to the granada spindles to do a disc. brake conversion. Also my car already has the dual master cylinder and distribution block. Do I really need a proportioning valve also. Thanks for the help.
