Before you go crazy about the welds, take a couple minutes to check if your Bus was build at THE One Affected Assembly Plant. Even if you find that you have one of these, you can have a welder fix the problems with little effort.
Go here for the rest of the story:
"The buses in question are Carpenter Type A, B, C, and D school buses built in Mitchell, Indiana
, prior to the plant closing in late 1995
.? It appears that the buses built at Carpenter's Richmond, Indiana plant do not have similar problems
Using the Vin that you posted, I got this information from a decoder. I dont think you have to worry.
