Hi , i performed a search but could not find anything recent which may help me with my question. I am hoping some of you have had experience with this.

I purchased a relocation kit for my 68 fast back from USCT Motorsports. I find out i need to fix the kit inline with frame rail which means right rear spring will come close to gas tank leaving me no room for exhaust pipe.

As it will be be a street / track car i prefer to have full exhaust to keep cops happy.
I am not keen of dropping pipes at diff or behind rear tires.

How have you gotten around this ?
- modify tank?
- is there another relocation kit on market that will give me more clearance for exhaust system?

Thanks

There was a Member here that had the same question last week, but it was about a 65 , I think... smaller car they are. Sorry I have no definitive answer. When you say inline, you mean just outboard the rails?
 
There is not much room. I bought a stain less tank and modified it and custom made my tail pipes

There are some pics where the exhaust mechanic went over the spring and exited outboard of the spring. Unless you move the wheel houses in you are wasting your time. Just go with the offset shackles if that is the case.
 
I used the mopar kit. If I was to do it again I would do it a little different
My tire is 390/45/15
 
I'm not sure of Your age, ain't none of my Business, so Please ignore my Slang! MAN, That's a Mad Killer Tire Tucked up in there! SICK! I Love It! You must be shoehorn'n in a Brutal Mill!!! Excellent Work! BTW, beautiful looking Mopar! Just Wow!
 
peterOZ , use offset shackles, roll the fender lip, and use 275 60s with the right offset rims to fit, and some cal tracs traction bars instead of butchering the car up. The 67-69 barracuda wheel well is pretty wide to begin with.

Besides the spring relocation, you will have to cut the inner wheel houses and move them in against the framerail. This will affect the finished cargo area and rear seat in your fastback. Dont do it!!!

You do not have to do any of this to fit 275/60/15. I run these tires with no modifications on my other Barracuda and my Duster that has the same wheel well.
I guess I butchered up my car?

Mini tub, and spring relocation. To me that's butchery. I just finished reversing an absolute mess done that way with aluminum tubs and pop rivets, so I kinda feel a bit strongly about it. Did not mean to offend.

Well I guess you answered his question then. And to add to that, a rolled lip and offset shackles and you can stuff a wider tire without spring relocation and mini tub. Dont do it!!! This is the mess I had to unfuck. Because of somebody else's exploits, I tend to feel a bit differently about that.

Thank you. It was a lot of work putting it all back to stock. I will do the last of the welding my next days off to put the C pillar roof to outer wheel house supports back in. They cut those out with a torch.

I hate back halved cars, and spring relocated mini tubbed cars. My thoughts on that are do that crap to a shot slant sux car. Preferably a dart or a duster, since they made millions of those. Wide as heck wheel openings on a 67-69 barracuda. No need for that, unless your doing really big HP numbers. For a street car wide sticky radials and some cal tracs is all you need. That's the plan with this one. Hell this one probably wasnt even fast. Never even had a cage welded in it. I bet I will have it run as fast as ricky racer did, but with a complete interior, and on radials. Now back to peterOZ and his regularly scheduled program.

The off set kit is enough to move your tire right up to the inside wall of the factory tub. Then you need to move it away about 3/8 inch for street horsing around. This leaves enough room on my 68 Barracuda, to run a 3" pipe between the spring and the tank, all the way to the back, both sides with no dinking around with the tank or it's positioning.
But, without narrowing the rear end, you will need custom backspace wheels. I run 295/50s on 15 x 10s no problem; all the horsing around I care to do.
I have run 325/50s on 15x10s in a straight line at WOT with no rubbing, but cornering normally. Those required a bit of hammer-massaging of the inner tubs in key areas; no big deal. And with my lowered body, I had to roll the lips, just a lil.

If you install the 3" offset kit, putting your springs into the frame rails, you will have other problems. Firstly your rear shocks will be about vertical, which will affect your street-handling, and secondly; HD shocks will want to rub on the front of the fuel tank. And you still have to re-engineer the rear shackle mounts as to their angles and range of motion.
With the shocks vertical, they offer no sway control, so then your system will depend on the springs, and their arch is likely to fubar that right up. So now you have to figure out how to mount a rear bar. If you don't control the sway, the tires will/may get into the fenders , the exact thing that you are trying to avoid. So now you are practically forced to mini-tub it and narrow the rear end. Going with the in-frame offset, is sort of an all-or-nothing deal.
 
1970 Dart, MP spring relocation kit, Accurate Ltd. pipe, 3/4 inch stack of washers between the factory insulator/hanger and the frame rail. Washers make it easy to exactly center the pipe between the spring and the tank. no muss, no fuss

That is a lot of work . Nice job.!!
Thanks for sharing
 
There appears to be a kink in my pipe that isn't in the OP's pipe that keeps the pipe parallel to the tank until it is past the tank.- don't know if that is a factor in the fit.
