I got lucky on my 72 Van tilt. I bought it on eBay for $119.00. I was the only bidder & the tilt PRND tilt indicator was broken also the clear plastic PRND piece looked bad (both available reproduction and fairly cheap) but this was about 10 years ago.
I did find these on eBay though:

Not exactly $119.00 delivered but less than a Chinese knock off and a heck of a lot less than a Flaming River or Ididit
