I carry two spares only drawback...
It was originally a 454 I pulled it and installed a Gm/mexico 350 4bolt main long block, used original 400 tranny and new 454 radiator it had a factory trans cooler..
Ok enough backgroung...
The 4th vin # is a 1 not a 4 the 5th digit is a 4 so the chassis is a standard 1/2 corrrect???
the tag on door post says 6000lb GVW.. I think it may have had an optional load package since it had trans cooler and heavy rear springs....

What I was posting about applies to 81-87's.
A 73 with 1 in the 4th posistion is a normal 1/2T, the 5th digit being a 4 means it is a pickup. If it is a long bed and a 73/74 I wouldn't doubt it has more leafs. Typically the 73-80's had 8/9 leafs.
