I have notice several different max weight amount for highway on M35a2 data plates. Can anybody shed some light on this? I seen 23,000 and up for numbers I think I have even seen 23,700. I can't read the data plate on my 1971 completely. I like the higher number so if anybody know where I get one let me know because today what it says is a big deal now unlike back in the day when you had a flat bed daully wrecker and they weren't trying tell you that camero on the back was to heavy.
