Hi, new here...
This site looks like an excellent resource!

My husband and I have an old Chevy step van, and are trying to I.D. the year & model.

I bought it in '87.
It had a '67 rebuilt motor and the shop owner said the body was older. The title says '67. Also, he said it was a former UPS van.

So far all I can find, after a lot of searching is this die cast toy from UPS.
(seen here)

It looks a great deal like our truck. (practically the same body)

Some differences are:
The UPS truck has what appears to be a wrap around windshield.
Ours does not, it has separate triangle windows on the side.
UPS has square skylights, ours are round.
UPS has a different grill, ours is a flat mesh-type grill.

Any help identifying the year and model would be much appreciated.

Thank you!
