I'm trying to find out exactly where the frame pads are located, I tried to find them on my 74 but all I could find was a continuous piece of rubber on top of the frame that runs the whole length. I thought the pads were 3-4 inches long. Just trying to find out if I need to replace or if they have already been replaced. Thanks in advance for any input or experiences.

Somme coaches used one continuous piece of rubber and others used the rectangular pieces you are talking about.

And please DON'T follow the instructions which say to jack each floor stringer up one at a time off the frame. Think of it... you would be trying to lift the whole side of the coach on one stringer! Most likely you will bend the floor stringer! I did this back in my early days as that was all the info out there. I ended up hear a loud bang and now I have waves on my drivers side.
Instead first you need to disable the suspension otherwise the frame will just follow the body upward. Set your rear suspension on blocks and the front end on stands. Then remove all the body to frame fastening (two J brackets along the side and a large donut at the front and rear) Also check for clearence between the Black tank outlet pipe and the frame since the black tank is mounted to the body. If you have a Ragusa step, loosen the mounting bolts on it. Also loosen the fuel filler pipe clamps that hold it to the frame because the front of the filler pipe is attached to the body.
Then using at least 2 bottle jacks(I used 3 I believe) placed under the stringers being the front wheels and ahead of the back (I used the 3rd jack behind the rear wheels), slowly lift one side of the coach from the frame. Just lift enough to get the old pads out and new pads in. As mentioned before, put a screw into the pad to hold it. I also glued it.
If you are going from thin pads to thick pads (as I did), you will need to makeup about 1/4 to 3/8" at the back and front donut mounts. At the time I could not find replacements, so I used large metal washers above the donuts to makeup for the extra height.
Just my experience.

Never having owned anything except '76's, I can't address the '73 & '74's
continuous strip frame isolators. But, to all those who have never
replaced the pads, let me tell you that replacing them will reveal MANY
rattles you never knew you had -- the coach becomes eerily quiet on that
first ride after the job's done.

73,and 74 have long continuous pads. I've never heard of them needing replaced. 75 , and up had individual pads. They were glued in, and fell out. I've replace the ones that fell out on 5 GMC's. It seems that the ones about half way back are the ones most likely to have fallen out. The main structural member for our GMC's is the body itself. The long middle section side rails has very little strength to it. Ask anyone that has had one out. You can pick up each side rail with one hand. I, as have many. Have used a floor jack with a 4X4 on it. At each floor cross member. The later pads are just under a half inch thick. You just need to be able to side in the replacement pad in. If your putting in thicker pads then what GM thought was needed. Then do as Bruce said. I've never seen a reason to put a thicker pad in. I have the approach that GM engineers had more knowledge, and R&D time then my. Or any of us. So I try to stay with things that don't change GM's basic engineering concepts. I've made some changes in our 78 Royale drivetrain. I put in the Quad bag system. Because I have a $1500 ramp hanging below the main frame. A 3:70 FD, Howell GM EFI, and the Benz fan. As these changes stay with in GM's basic engineering design parameters. I'd never put wheel spacers, or the 1 ton system in. As they don't meet long term SAE design standards. Bob Dunahugh

My '75 (TZE165V101455) has the continuous rubber strips. I have never felt the need to replace them. Every once in a while, I check them and, if necessary, drive them back into place if they have slipped to one side or the other.

I drove my coach up on a set of ramps that put it 8" off of the ground. Then using a bottle jack and a 2 X 6 X 6, one at a time I placed the jack at the points on the diagram that Emery posted. I then very gently jacked the body up just enough to remove the old pad (if there was one) and slid the new pad in place. I then screwed the new pads in place with several self tapping screws so they wouldn't move. I never even bothered to loosen the body mounts. I dreaded this job figuring it would take the better part of a day. Once I got the coach on the ramps and got the tools and jack together the actual replacement of pads took about 45 minutes. That was 12yrs ago. None of those pads have dropped out or even moved a little. JWID

I used 1/2" horse mat from Tractor Supply. I don't recall the measurements
of the mat but at $25 dollars I had enough for five coaches.
Each pad measured 4"x5" .

Don’t you just love it when what you did appeared to be “best practice”?
I used cut in half hockey pucks for the spacer.
It’s a vibration thing, so the fact that it is does most of the work (as opposed to the damping factor of the material)
