Profab k-member, Mustang Rack, exhaust issue.

Got my profab k-member in car. Motor in car. Hedman headers and mustang rack. But the hedman shorties don't work with the steering shaft. The #5 primary is just in the way.

You guys who have tubular K-members, and headers, and rack & pinion. What are you using for headers? Got any pix?

I don't have a R&P but I still had clearence issues with my large tube headers. Nothing a big hammer to the tubes didn't fix. I only had 2 tubes that were causing problems and the worst one was #4 cylinder. The tube is dented so much now to go around the Profab K-member it looks like the k-member pipe goes through part of the header tube.

Many factory headers have strategic dents to clear components. The BBC Hooker swap headers have a dent to clear the steering shaft right from Hooker.

Right now, the routing is just not possible. Denting wouldn't help, it would need to go right through that primary.. I'm not really sure what to do. I'm stuck..

I'd love a R&P but I'm in the same boat. The header tubes with the BBC are just so big that it's impossible to route the steering column through the tubes to where a R&P needs to be hooked up. Even now I had problems running the lower part of the steering column. I had to relocate it on the firewall outward and upward about an inch just to clear the header tubes.

The lower part of the steering column doesn't have to be a single shaft. I've seen custom fabrications to get around obsticles but using 2 short shafts with an extra u-joint and a support. I'm not sure if you have enough room for that but you probably do. It's not cheap though. Good steering shaft u-joint couplers are around $50 each plus the shaft, support etc.

Yeah I've seen similar setups. I'm gonna put the tranny in and see if the angle of the engine improves enough to make a hammer and pry-bar worthy.

Thanks.

If anyone else has. done this with the rack & k-member, PLEASE tell me what headers you have.

I had talked to Flaming river about making a custom 2 joint setup...suprisingly the cost was not that bad>>I did not end up doing it...BUT basically they wanted me to spec out how the bracket/support shaft bearing setup wuld look and then give them legnth dimensions... It all sounded very easy to me>>>But I got extremely lucky with my custom turbo headders to where the arm just barely clears... No dents..

I have that exact same profab setup.
the guy I bought it off of had to dent one primary to clear the shaft, that was with long tubes on a small block.

my turbo setup is nothing like that though!

the one thing I don't like about the mustang rack is I have no turning radius at all!

probably going to be your best solution for budget reasons, let alone anything else.

You would think that ProFab used a set of headers for mockup when they designed the K-member. Has anyone called them to see what they used?

Come on down, your welcome at my shop anytime brother!

Car runs now. Need to adjust valves and stuff, and just mash the rad support a hair more for the intercooler.
