Do you have a rear sway bar?

I never put a sway bar on it. I don't have it anymore, and didn't drive it enough to know if it needed one or not.

On Malitude it was a narrowed rear end, and I'd guess Mark did the same. If you minitub but keep the rear end stock width you end up with wheels with no depth to them. In other words, they'll have to have a lot of backspacing to be wide and still fit. If you narrow the rear you can get a more centered wheel offset which I think looks much better.

Jody

then that calls for some rear end chopping. thanks for the help.

btw, do you know how much per side to narrow the rear end?

that would depend on wheel width and offset as well as tire size. Best thing to do is complete the frame and tub mods, get the wheel/tire combo, set them in place and measure for the rear width.

Thanks for the good info and pics
 
Great info, I love the pics.

Did either of you guys do this on a frame table?

@Mark, looks like you used boxed frame rails behind the rear axle body mounts. Is this 2"x4"?

Thanks, Josh

No, just welded in some braces before cutting, and measured before welding.

That's just the factory frame in the back that I boxed. :cheers:

ben there doing that
 
I'm working on a 65 chevelle , 64&65 have very small provisions for tires (The frames are the same 64-67)1966&7 have a lot bigger wheel well.I took 2" out of each side of my frame( I notched it) replaced it with a 3/8 plate.You cant take out any more than 2" (upper spring perches are right there) I also had to move 2nd to last body mount.By notching frame instead of moving it. I was able to keep stock gas tank factory upper and lower bars.(no frame jig required. My wheel opening measure out to 13 3/4"now. 66-67 cars are wider so it would measure out more. I have a lot of pics . they are to big to send?(I'll try to make them smaller)Or maybe I could send them direct to your e-mail.(I'm not very computer savy)TIM I'm doing min tubs right now.(419)371-4955
