Doing a frame swap for a 97 4.0 to a TDK frame without mounting holes and I got rid of my frame a while back.. took lots of pictures but didn’t measure that. The fsm provides frame dimensions but no mounting locations.

Can anyone give me rough dimensions on the mounting locations for the two exhaust brackets on the passenger side frame rails?

The mount just to the rear of the muffler on the exhaust pipe I believe is supposed to be close to the rear sway bar frame mount on the inside frame rail with two bolts. The rear most exhaust bracket is on the outside frame rail and is also mounted by two bolts.

With the new stock exhaust I can get things line up pretty well and clear the rear track bar, and passenger shock boot. Had to bend the exhaust tube hangers a bit. Just hoping to get it as close to stock as possible.

A good measurement point between both frames should be the sway bar link mount.
Thanks!!
 
Hope someone reply's before. I got to work today and have a frame with what you are looking for but not home till next Tuesday. Sorry
 
No worries; I really appreciate it. Having good measurements is important!
 
Here ya go, hope this helps had my wife go out and get them. Of course that was funny she called the muffler hanger a small pen$# looking thing :ROFLMAO:

I would have to look when I get home next Tuesday the only other exhaust hanger is on the drivers side on the control arm bracket. Not a great shot.

Thank you! I really appreciate the check and pictures. That must be from the drivers side otherwise I'm not seeing where the old exhaust hanger bracket used to be. I was able to find a junked frame here and grabbed a few measurements and ill put them below should others need them. If I can find a picture of the middle exhaust bracket still installed, Ill post here.

Rear Exhaust Bracket:
- Rear bumper (center of bolt) to bracket (rear edge) = 10"
- Rear tub mount (hole center) to bracket (rear edge) = 9.5"
- Rear passenger sway bar link frame mount (bolt center) to bracket (front edge) = 24.625"

Middle Exhaust Bracket:
- Rear passenger sway bar link frame mount (bolt center) to middle of bracket bolt holes = 2.375"
- Bottom bracket bolt hole center to upper edge of frame = 2.125"
 
Dang it man this frame is upside down lol I took a picture of the wrong side what an idiot I am :rolleyes: . Sorry about that!
