Two of the forged overload spring travel limiting brackets in rear had broken off and home-made ones installed. Each of those were grooved underneath indicating this truck was terribily loaded a lot.
There are better trucks around. I'd still like to de-cipher the VIN.
Dennis [/quote]My grandfather had a 47 Advance desisn Tractor said he tried adding leaves to overload springs but then it would just break the ears off so then he built up the main spring. it was not uncommon.
