Title: Exhaust body hangers
Post by: dave73 on September 19, 2017, 07:00:56 PM
I have a 73 challenger and when I bought it, it had some jimmy rigged exhaust that I removed. I don't see a hanger bracket on the passenger side under the rear seat, do 73s not have those? I was expecting to buy the drivers side bracket and be good to go, but I don't see the dimples to drill the holes on the driver side either? Looking for a simple solution, should I just buy the 70 brackets?

Can you post a photo of what yours looks like?

73s use these hangers on the passengers side.  They mount on the shock x-member.  Look for a bracket welded to the shock x-member where this hanger mounts.

Burdar - I don't have that hanger on the passenger side. Very likely the previous owner removed it when they did whatever they did to the exhaust.

I ended up having a body mount for the drivers side in a pile of old parts I ordered. I installed that last night, worked really well. I may order another one for the passenger side, I like the way it worked out

Like @Burdar (https://forum.e-bodies.org/mlist/burdar_173) said you can just get the right side hanger and it will bolt right in. No hassles. There should be a spot on the shock x-member for it to bolt right up too. You can put a floor pan bracket and another lower main support hanger on the car but you might be creating unnecessary work for yourself. If you do put a floor pan bracket on it you would want to do it after you have all the exhaust hung on the car to insure proper placement.

Here is a link the the proper hanger for your car:

Are you going to put factory exhaust back on the car?

It looks like you've changed that hanger since I bought mine.  Your hanger now has the correct strap and bolts. Mine came with the wide strap and was attached with studs/nuts. It's nice to see that you made it more "correct". :bigthumb:

Does anyone have photos of both (left & right)  bracket/hangers installed, but before the pipes are hung?

Thanks!

I wish I had taken more photos of the exhaust when we took the car apart  ::)

Here is a pic of what is left of the hanging hardware

Here is a pic of the area under the back seat after the axle and fuel tank were removed; pretty weird setup there  :rubeyes:  The car came with dual exhaust but there is only a pipe hanger bracket under the seat on the drivers side, none on the passenger side.  Someone lag bolted in a "tether" to the passenger side floor.  I can't seem to find a definitive diagram on exactly what hardware the car should have, and where it mounts. :dunno: I am pretty sure that tether on the drivers side is wrong too.

You have an interesting mismatched group of parts there...... You have a pair of 74 rear mounts, plus a set of 70-73 rear mounts... You have single proper 73-74 over axle hanger plus you have a 70-72 drivers side muffler hanger & the passenger side if it is a 70-72 should have a similar bracket welded to the body...

I am not sure what the deal is.  I know the car is a '72, or so says all the Vins I have found in the right places, the 2 fender tags, and the build sheet I found on the glove box liner.
I think the car was wrecked at least once, maybe twice in it's lifetime; some really weird patch jobs found during tear down.   Maybe a shop took parts off other year cars to fix it?  The exhaust resonators were removed at one point leaving only the mufflers in the back.  I will measure the pipes again. but I think they are 2" all the way back.  In the aftermarket I see only 2 1/4" ??  The new tips I bought are 2" .   I read somewhere a while ago that the right and left pipes were suspended differently in the back, and that there was no floorboard bracket on the right?  :dunno:

I have the car posted here too:  https://forum.e-bodies.org/your-restoration-project/10/our-72-cuda-project/3731/msg55692#new

I appreciate the help sorting this out to get it right  :bigthumb:

One minor correction. Mid 71 and up don't have a floor pan bracket welded to the body on the passenger side as they moved the hanger to the shock x-member support. Lower hanger on the drivers side is correct though.

Well that makes sense why there was no fixture for a hanger under the right floorboard; I'll have to figure out the x-member mount.  Hopefully the vendors know.

So, does that clamp there secure the pipe, or does it support another piece of hardware that holds the pipe?

Two bolts mount it to the crossmember & it supports the pipe..
