Also, it's doubtful that your truck came with a diesel as the diesel came out in '79 (at least in Canada) and if it were a diesel, it would have a hydroboost in it rather than a vacuum brake booster, unless you changed that.

Diesels came out with the 5.7 in 1978 i ran my vin and it is infact a diesel truck it did have a have a hydoboost and i replaced it with a 84 booster it had all the factory wiring for the diesel under the dash and has the diesel bezel for the glow plugs %100 diesel (WAS) :-)
