No worries about haveing heavier springs in the front. The first GM diesels were 350 Oldsmobile gas engines with diesel heads and a beefier crank so they shouldn't weight much more (if at all) than any other Olds 350. 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.
