How much "offset" do offset UCA shafts give?
I have added a spreader bar on my car and the threads are flush with the end of the nut.
I'm considering getting the offset upper control arm shafts but I wonder how much offset they are. Can anyone who has them take a rough measurment for me?

I'm a little confused. You mean the threads of the spherical joint
are fully covered with the bar and lock nut ?
I thought the "offset" was a rearward offset, which shouldn't
affect the distance between the two shock towers.
A picture or two sure would help.

Sorry,
Here is a pic of a UCA with an offset shaft. Basically, it moves the UCA towards the engine giving more neg camber than a straight shaft would.
My problem is that with the spreader bar bolted on after the UCA, I have no extra threads sticking out of the nut, so the offset shaft would allow me to remove some shims and give me some breathing room.
Here is the pic. Beware dialup, it is huge.

Get a set of Mr Gasket, Moroso, or ARP drum brake 7/16" long wheel studs and change them out with the factory GM upper control arm bolts (they have the same knurl as your stock upper bolts but, are fine thread instead of coarse like the stockers.) I did this to get over 2 degrees of negative camber on my LT-1 but, if you are not going to use a spreader bar, don't use the long bolts! they are too weak without the additional support. The Moog upper control arm offset shafts tend to add about 1.5 degrees of additional camber compared to the stock shafts and might be a wise addition too.
