Chevy & GMC Vans

Does anyone have a directory if the combinations available for swapping the nose pieces and inner radiator support and bumper pieces 1971-1996?

Welcome,
I really don't understand your question, are you looking to swap noses, same years, same style or swap from first to second generations?
You see the 1985 -'94 are first gen, '95 - '02 are considered second and third is 03'- to '05.
'95 - '05 are the same body style throughout but some of the running gear changed.
Second gen noses have been swapped to first gen vans and documented on this site.

one I found, front end conversion(older van----newer clip)

Hi Wood butcher. Thank you for your reply. The link you sent I believe is for the astro vans. Looking for full interchangeability directory of all g series 1971 to 1996 of the nose pieces. For example, some have single headlights some have dual headlights stacked on top of each other some have dual headlights horizontally. Then there's the issue of the bumpers the earlier ones have a smaller bumper, the later ones have the larger bumper. So I'm looking for an expert opinion for example if you have a 1978 nose, to swap towards a 1990 body. Or if not all the pieces were present what could you use to make it work. A full directory of the parts interchange would be helpful so a user can find the pieces as they are able to make something work for themselves.

That would have been helpful to know at the beginning. Please make sure you provide all relevant information with your question. Thanks.
Moving your question to the G-van section.

Ahah! I see now, I thought you were after astro info. It is one of the mods I've given serious consideration for my '93.
I had an '87 Beauville model w/ the stacked headlights and chrome grill. It was beautiful compared to the base model w/ a single sealed beam so I can understand your hunt.
Here is another site you could check, maybe you'll have better luck with the search function than I did.

Or wrecking yards I know used to keep that kind of info, try asking at your local pick 'n pull.
