69 Cougar rear frame rail patch

Hi all I’m looking for rear frame rail patch’s for my 69 Cougar. I found some on summit I was wondering if anyone one had ever used these or had any experience with something else?

Or maybe some other ideas? what’s on the car has bad rust in front of the rear leaf springs

My experience with Cougar frame rails is that they are mustang frame rails and short behind the shackles by 2” or so

Yes they are short behind the shackle and there rusted almost in half were they are braced in front of the shackle I wasn’t sure if the summit part had the correct bend in them or not. I’m thinking of giving them a shot I’m sure shipping will be expensive but I might be surprised.. The pair are relatively cheap!

The Mustang parts won’t fit at all. You need real Cougar parts. Try WCCC they have what you need.

Thanks @Royce that’s what I was afraid of Thank You for saving me the grief of wasting money on those parts. I was very leery of those Mustang parts. they didn’t look right in the picture. I’ll check with WCCC. Thank You again for your help greatly appreciated..

It may not be cheap but the parts will fit.

Thanks @Royce I did look at them and they are definitely not cheap and I have not ruled them out. I didn’t get a chance to get out in the garage today. But I was wondering if I could cut out one side at a time to clean good metal and weld some new steel plate in its place or do you think that would make it too weak? I don’t know if that is possible or not and if it is too far gone. It would certainly save my pocket but if I have to replace it that’s what I’ll do..

Thanks for your help and I really appreciate it Royce.

I think you need the parts that WCCC sells. Raw sheetmetal would be too flat, these parts are made of many curves.

Agreed @Royce after I was able to get under the car today and really check it out good I think I’m going to see what I can find in my area before I make a move. Another speed bump in my way Ugh! I sure do appreciate your help. Thanks Royce

Hi!
I had the same issue with my 67, so first I sandblasted them from outside and they look pretty good but when I finally removed the trunk floor the inside part of the rails where worse than the outside.After that I was looking for frame rails, nobody made them, so I ordered two mustang rails and I said that I would modify them to make them Cougar; it turned out that I wasted $1000.So my last option was to order them from WCCC and clean them and repair them since those I received were in very good shape but not perfect like any used parts.It’s a costly task but at the end the results were excellent.I ask WCCC to cut them to save $400.00 in shipping since the uncut ones are oversize.I just had to make a splice and reweld them together.Good luck

Hi mike289 Thanks for sharing the pictures they look really good and you did a nice job on cleaning and welding them back together. Thanks for the tip on having them cut $400 is a good saving for sure I have no problem welding that for sure.

I appreciate the information one of my friends has a line on a couple rear frame rails hope to find out more about them and go look at them maybe I’ll get lucky not holding my breath though..

Thanks again Mike289 you’ll have to post more about your project

I would think these could be made out of tubing. They wouldn’t be exactly like the factory made them but should work . Cornfield customs in Ohio has a tubing bender. He might be able to bend them if he had a pattern.
