Re: 80\'s chevy vans
also search for models such as nomad, vandura, beauville, chevy van, sport van, conversion van, etc, those were model packages of vans throughout the years, there were tons of conversion package names, they were painted on the exterior somewhere usually,. i have owned quite a few vans, all 74-79 years, soem super shorty and some extended length, there were a bunch of different wheel base lengths available for vans and engiens from 400 small block down to the 250 straight six and with three speed manua, th350, or 700r4, ive had at leats oen van with each of those three trannies,
G10 are lightest 5 lug 1/2 ton van, G20 are heavier 5 lug 1/2 ton van, basically 3/4 ton but with 5 lug still, then there were the G30, the big heavy vans, usually with 14 bolt FF and same or longer wheelbase than the longest G20 vans
my last van was last summer, was a 77 G20 long van, originally 400sb and th400 and when i got it it had a 76 pass car 350 2bbl and th350 in which is now in the 82 trans am
a neighbor of mine has an 82 1 ton dually van with box, its huge but is normal 16" dually 8 lug setup, just that the 14 bolt FF is way wider than pickup burb ones and leaf packs separated farther apart than other trucks
if you pop hod on most years of vans there is the SPID label glued to botom side of hood on driver side and will tell you axle ratio, engine, body package, etc,.
thats all i know right now, email me if you need any info
