1977 Dodge B100 Van Floor Shifter

Anyone know where I can get a 3speed with overdrive floor shifter assembly for a 1977 Dodge B100 Van. I'm not sure if it's called a 3 speed with overdrive or a Overdrive 4 speed. It has the H pattern for shifting.
Please help. Not sure where to look..Thanks, Jackie

You might try your local speed shop, they should have a lot of different shifters there. Other than that, check with the original manufacturer of your shifter (if you can still read it) or check with a major supplier, like B&M or Hurst.

Good luck, I know your van is a rare one!
