72 Demon Power Steering Gearbox/Coupler Help...?

Call Flaming River industries. The factory coupler would not clear the headers on my big block Duster so I bought a nice stainless steel U-joint coupler from them. Its best to call them directly because there are variations in what came on these cars as far as parts like steering shafts etc. 440-826-4488 or 800-648-8022. Their coupler is far better than the factory one.
Thanks for the information. I will give them a call next week. I am not able to get a roll pin to stay in now, so I have to get something figured out. Thanks again for the information!
