Frame stiffener, overlays longitudinal, Anyone here install a set ? Options

[Luke M]

I'm getting ready to work on the 6 now that the weather is getting nice again.
One of the major projects that needs to be done is the repair of the r/r outer long.
I have most of the metal to start the repair but need some advice on the installation of the frame stiffener kit. This is also known as the clam shells and sold by restoration design. Has anyone done a step by step install for these?
I thought there was something on the r/d website but it's no longer there.
I know that I need to measure several points on the car prior to welding to confirm it's straight. I'll post pics as I go along with this repair.

I have a set on my rack of parts to be used on my restoration.
I'm not seeing folks using them much.
Now a days. Folks dig a little deeper than they did a few years back.
They want to cut all the rust out.
I don't think I'll use the set I have at this point

I see the stiffener as more of a band-aid for the person not wanting to get to the bottom of the problem. Short term fix
If you don't cut out all the rust. It will continue the eat the car apart. My .02c.
IMHO you wouldn't want to use them on a 914-6. It will create additional issues when the increasing value on the car warrants a complete restoration. Once again, my .02c.

As for installing it. The door sills have to come out so you can weld the top seams.
Looking at mine a couple times. The biggest issue I see is getting a good surface on the bottom seam. Pretty bumpy It needs a good flat surface.
Drill your spot weld holes and your good to go.
Don't forget to use weld thru primer.

Sorry for being so blunt. But I play all my cards face up ...............
