Hey Tony,
Thanks for the info.
The original floor mats in the 61 I'm restoring are different than the ones at Classic (39-021, a one piece mat)
The original mats in this 61, are two mats (Left and Right)the center hump (4spd)has no mat covering and has original black paint. the two mats are held in place by round metal pegs attached to the cab floor. The far left and right edges are tucked under the sill plates.
The reason I logged onto StoveBolt was to seek help in finding parts that are as close to original as possible.
So again, thank you for your observation and suggestions.
Since you are so convinced you have a factory-correct split rubber floor mat, don't change it, because you have the only one ever produced and, therefore, it must be priceless. I have purchased NOS floor mats for the '60-'63 Chevy trucks and they were full-width, just like all of the other OEM rubber floor mats, produced and installed in the '60-'66 Chevy/GMC trucks, Panels & Suburbans. I see with your 16 posts and your '61 Chevy Apache acquisition, you have rapidly gone from a newbie, to a self-proclaimed expert on '60-'66 Chevy trucks.
Good luck to you with your project. I will refrain from sharing information or contributing to your threads, in the future.
FYI, all of the truck cabs, had pins, to secure the floor mat and the mat was tucked under the door sills. Your mat was cut and the hump painted, so buy a new rubber mat and do the same, since you are certain this is the way it came from the factory. Retaining orginality is great, as long as you actually know what is truly original.
