Flaming river columns.

Hello new member first post outside the welcome section threads. I have a 72 duster that came from the factory with manual steering. I bought the cat as a rolling chasis and it has a lot of nice suspension and chasis upgrades. Interestingly it has an electric power steering unit which works pretty well when I hooked up but I don't think I want to use it. I am planning on a 408 with manual transmission and I think it will interfere with a clutch. The car is factory automatic but looking at 4 speed car pictures inthinknthe electric motor under the dash will interfere. I also plan to get a flaming river colum qith tilt. To get to my question I plan on using one of the new more compact borgenson ps units and was wondering if anyone has one of those installed with tti headers and could give me some guidance on clearances with that set up. Also has anyone used one of those units with a flamingnriver column? Thanknyounin advance
