Last 1.. Anyone Identify NOS trim # 3811246-7

Since were covered in ice here in Pa...I have been trying to identify what's left of a truckload of Nos trim parts I have had layin around. Musclecar ones are easy to identify and find but some are
These are a beautiful pair of what I don't know...They are dated 6-9-76 & part #'s 3811246-7 so I am thinkin a 1975 model year cause my '74 books have nothing...Thanks in advance...Pic to come soon..

Here is what they look like...2 studs on back and 1 ft long..

for the evening crowd.....

They are not in the '75 '76 '77 or '78 passenger car catalogs or '72 truck either.
Are these numbers on the wrapper or on the part themselves? Check the wrapper.

Looks like trim pieces for two-tone paint or woodgrain wagons, but since they aren't in the passenger car catalogs I'm thinking pick-up or van?

Thanks they are on the dealer ticket attached to the wrapper and they are cast into the potmetal...the one 3811246 rh also has a cast # of 3811070 before that # maybe that will help...

Not in the 72 or 73 Car either

Everyone is having the same trouble identifying these as I am.....Thanks for trying. It drives me nuts cause I have about 100 more to figure out...
