Hey Mike,
I have added more pictures to my photobucket of all the numbers I could find in the vehicle.
The tag on the firewall has weathered off all paint, but there is a stamped number on the right bottom corner.
It is: LR 8982
There appears to be a number before the LR, but not sure.
Could be a 5. Check out my photos
There is a number stamped on the block.
It is: TI 91426
The truck doesn't have dual wheels on the back.
It is a six cylinder.
