Front Suspension

[1969 modified]

I have recently aquired a 65 chevy LB to set beside my 69 SB. I have been taking it apart to completely restore it. I have found that GM used the same frame and suspension on these two trucks except one is a LB frame and one A SB frame. My Questions......

1. I have a complete disc brake set up that I removed from a 72 5 lug truck. Can or has anyone used a 6 lug rotor that will fit the 72 spindle? I prefer to keep the 6 lug set-up since I already like my wheels. If I remember correctly I would have to change the upper ball joint and the outer tie rod end on the 65 to accept the 72 spindle???

2. I would like to lower the 65 truck. On my 69 I used coil clamps on the rear to lower the truck to level height with the front. I could do the same on the 65 rear coil springs but I was wondering if I bought the shortened front coil springs to bring the front down as well, will the 65 truck be able to be aligned properly on the caster/camber adjustment? Sometimes you run into the adjustment bolts for this alignment, is not long enough to make the correct alignment. I'm sure someone has attempted this solution by buying the shortened coils springs. Could you share some info please?
