Actually i think even the head is 54.

The LEA number was only on the paperwork and i have not found it on the truck... so i don't have a bill of sale or registration that actually matches anything. that's my concern.

previous owner must have swapped engine and cab. but even the engine before that must not have been original because the chassis is a 54.

and on top of that the cab apparently has a 53 serial number but is unmistakably a 54.... cab number is X53T 05768.

HELP ME!!!!!! HA!
