1970 C10 Suspension Questions

[vexvader]

1.) I have a 1970 C10 LWB & SWB. I wanted to take the traling arms and rearend out of the LWB and rebuild them and put them into the SWB. They are both 12 bolt GM. Will the LWB arms and rearend bolt right in?

2.) The top A arms in the front are loose right were the upper cotrol arm shaft goes through it. When I jack the front end up and shake the tire, the top A arm moves about 1/2 inch. I noticed that you can order just the upper control arm assembly and the top A arm. I know it will be hard to say for you guys without looking, but do you think I need a new A arm or just a new arm assembly?

If I need a new A arm, what are the advantages of upgrading to a tubler one from like CPP?

For clearity, I am using the LWB for parts. I want to put the LWB rearend into the SWB. I could also use the A arms for the LWB for the SWB

Thanks, Vex
