Reading the latest thread from our GMC guru Bill Bryant, I was intrigued???since I will be dropping the tanks this spring, is this a "while you are at it" job...if the tanks are out will it be easier?
My '73 has the continuous frame pad, but I am missing the cross member pads. I could assume that the continuous pad has so much more surface area carrying the weight of the body, it would not compress as much to require replacing. I noticed while installing my reaction arms, that there was plenty of room between the frame and body at the fuel vapor valve and air suspension line area. ( not pinched)
But have decided to ask the collective GMC hive...
Has anyone replaced the continuous pads on a GMC? How bad were they?

I did one one time with someone else on a 4 post hoist. It was a bear of a job getting the old ones out. We ended up using a cable hoist attached to the 4 post hoist to pull the things out like you would do pulling a chain link fence.
The rest of the job was simple. I would not recommend do this unless absolute necessary. I would then consider putting the new pads on top of the existing strips if possible. I have never done it that way.
This one also had the 4 bag rear air system. We could not get in behind it. He said he would remove the 4 bag system later as it was bent and needed to be straightened and beefed up anyway.

Sean,
My '75 coach (last four of VIN - 1455) has the continuous frame pads. It is as you describe with plenty of room for fuel vapor and air lines. It is also nice and quiet inside. I have no plans to change them out for individual pads.
