hello Jeff
Last year I picked up a 97 patriot yorktown on a magnum 8 air bag chassis which also had torque rod issues from age and sitting.
the seal boots on these torque is a semi silicone piece which was crimped on at the factory and the ball end it protects was formed and swaged in at the factory.(not replaceable)
the torque rods are a ZF manufactured design and can be bought through BCS But after a lot of research I discovered that
Freuhauf trailers used these years back and a two piece version (weld together) allowing for custom length can be found at Michigan truck spring on line
https://www.truckspring.com/heavy-duty-truck-parts/suspension-parts/freuhauf-torque-arms-rods.aspx as TS 345-812 for $271. USD
These should be assembled in place and tacked to achieve the proper lenght and the removed and welded I have installed one in my coach and it worked perfectly.
But before you go to all the effort and expense check to made sure the rods are worn out.
Mine have most of the seals torn or missing and I had several rhat had siezed ball end which squeaked and or moaned when
they moved (on every bump.)
I removed the torque rods one at a time and cleaned them up and in a vise lubed them with penetrating oil and worked them
until they freed up. (It,s a big job but all but one was reusable )
After I freed them up I drilled and taped each end and installed grease fittings
I also found boot kits to replace the originals These are ZF part #68324854 and are originally used on ZF brake calipers
they aren't perfect but they work and even look like the originals
After I was done the front end sounded and worked 100 percent better
Question
does your coach have two front shocks or 4
If it has 2 check carefully at the frame where the brackets for the upper shock mounts are bolted,
on these coaches they have a bad habit of cracking the frame through the bolt holes (poor design)
if so the mounts can be taken off (unbolted)
the cracks drilled and welded
and then the mounts welded to a larger 1/4 inch plate which is then welded top and bottom to the frame (no vertical welds)
the plates on mine are approx 2 feet long and 2 inches shorter then the height of the frame rail leaving about an inch top and bottom for the weld.
My coach had the drivers side done when I got it and I had to do the passenger side.
with that done everything is working well.
Hope this helps
Eric
