91 yj frame rust help

So I got a 91 yj renegade for 1400 last summer. Live in Iowa so knew rust would be a problem. No floors so since I work in an aluminum plant I got some plate and fixed those up. Now to the real fun, I am planning on doing a small 2 to 3 inch lift by swapping leaf springs and shocks. But my rear frame is rusted through where the back shackles hook up to leaf spring. Do those repair patch/plates that I can order from quadratec work good? They are $100 + each or should I just weld in some steel plates and call it a day. Rest of frame looks good but not driving it now and will be putting it under the knife real soon so I can begin the lift process.

how do these repair parts work - from what i have seen they slide over the existing frame and you weld them in place? wouldnt that make the frame wider and then the shackle would not fit over it?

Im not familiar with the patches ur describing. I personally make my own patches either out of 1/8" plate or angle. Cut out all the rust & attach the "home made" patch. By home made i mean fabricated. With enuf time & effort, the repair could look factory again. Hope this helps !

You cut out the rust, slide the repair piece on the shackle location stays the same with. Hope this helps.

I just had my rear frame repaired on my 91 Renegade in January. I bought the shackle area pieces from AutoRust.com It's called "Safe T Cap". They were fabricated nicely. Steel was .117" thick and pre welded nicely. I had the local weld shop drop the gas tank and weld them on for $300.

I bought the SAFE T CAPS for both sides if my rear frame and had it welded to repair some serious rust. A long as the top 1/4 or so of the frame is solid enough to weld to they are a good fix. Just mark where your original shackle holes are.
