Ya, the tilt column I used from the '78 CJ also had a smaller, non-bus wheel...
this pic shows the column installed, with the wheel tilted all the way forward
Yep, the '78 column had a 4-way flasher switch. The wiring of the column was standard GM.
Flaming River has some column and floor mounts you can use... some hot-rod places carry mounts like that too.
I think Flaming River and Centech both may offer fully rebuilt tilt columns.
I've also heard of guys using some XJ - Cherokee columns, which are about the right length.
