My aluminum coupler was a bust for 2 reasons. My mechanic is a stickler and since the Bouchillion packaging says "for off-road use only" he didn't like and it didn't fit right anyway.
I did, however, luck out and found a guy with a storage unit full of 65-67 parts! I bought a complete
tilt floor shift steering column complete with a really good oem coupler. I'm going to clean it up and try to install it, and we'll see if it realigns my wormshaft at all. If it doesn't, there must be an incorrect steering box in the car. I'll address that if I have to.
