i have a buddy make his own stering shaft with two little u-joints on each end and a short piece of shaft. the little ujoints came out of caprice classic police cars. it looks factory! he's got a 54 chevy car on a 78 firebird frame and had to make his own shaft , he was going with flaming river joint, until he found the police cars had the same joints in them. but only one per car, he found a second police car about 30 min later in the same yard and got the one out of it so he had the parts needed to make his steering shaft, that looks like a z straightened out, more of a zig-zag. i don't know if it was the police cars or if all caprice have them,worth a look tho if you need those type of joints.
