caster question
I have a 66 bb and I am having trouble getting enough positive caster.
I am running radial tires and power steering.
With the camber set at 0 the most caster I can get is ¾* of positive caster. I would like to get the caster up to 2-2.5*.
All the control arm bushings, and ball joints are good . Will a set of offset upper control arm shafts solve my problem? If so, any recommendations for part companies.
Thanks
Steve

A simple solution is to remove the upper a frame and take it to the machine shop and have them elongate the 2 holes in the cross shaft 1/4 of an inch and then your front end shop can dial in 2 to 4 degrees caster.
I have been running 4 degrees for years and it really gives the car directional stability.

Thanks for the idea. Do you know how they incorperate the offset in the replacement shafts. Do they just drill the holes in different places or do they offset the ends of the shafts.

They offset the ends of the shafts.
silverslashstreak: your approach is interesting.. did you have to fill the space with anything or is it possible to hold it tight (from slipping fore and aft) just tioghtening the nuts?

If I have .30* +camber and .60*+ caster no shims in the front and 3/16 in the rear. How much caster increase can I gain with these offset shafts? I want to make sure I get this close to what I want. ( 2 1/2*-4*=+caster) . I like the idea of slotting the holes in the shaft but I want to weigh all my alternatives. I don't need to go back to the alignment shop 2-3 times.

You can make up a little shim out of anything laying around the shop. once you slip it in the void it will be captured by the shims on the back and the nut on the front side.
I think it is the most cost effective way to increase your castor and still retain stock bushings .
