how much rust is too much

My cj7 has four rusted out body mounts (on the body). Other than that the frame and body are pretty solid for a 77 that spent time in the northeast. It is by no means rust free but appears salvagable. The problem is that I can't find replacement body mounts in any of the catalogs. Is it too much work to fab these up or not. Basically the two rears and the passenger side middle are completely gone. Any suggestions would be appreciated.

Re: how much rust is too much

for the rear, buy a completely new rear crossmember. they are around $60 from Four Wheel Drive hardware (www.4wd.com). as for the middle ones, i cut the rusted ones back far enough to get rid of the rust. then i took a piece of 3x3x3/16 square tube and spliced it into the rusted out mounts. i cut the sides of the tube at an angle to match the original mounts so it is basically an up-side down "U" shape. i have some pics attached (hopefully). matt

Re: how much rust is too much

Quadratec should have what you need, or you could try Classic Enterprises, I think the address is classicent.com. For body mounts the good low-buck fix is just a piece of a plate with a channel or some other supporting structure underneath that you can tie into the existing body supports. I have replaced whole Jeep floors with 16 gauge and few pieces of light 3" structural channel.

Re: how much rust is too much

Well, I thought my tub didn't have too much rust, until I started digging into it more and more. When it was all said and done, I had replaced everything outside of the red area. I'd poke around more to see how things actually are and not just appear. I found rust that was between the two sides of paint, yet it looked normal from the outside.

Re: how much rust is too much

jeepn is right once again! on my tub I thought it was only a little rusted and the rest was just surface but before I knew it the whole corner behind the driveside and passengers side had to be replaced and up front right underneath the jeep a lot of the time rust is inbetween the two pieces of metal and doesnt take long to eat through.
