Thanks very much for the answers...

OK, I know what the part number is but it doesn't appear to be in the CMP Chev parts book, so I was hoping someone will have a book with it's true purpose noted.
Group 1205A Part 2417140. The part number was not quite distinct on the pack.

It's a spring, about 20mm or 3/4" long, painted Chevrolet engine grey.

What it is similar to is the spring on the front bolt on a cab where it meets the bracket on the chassis, under the hole for the the crank handle, although it is slightly thicker and shorter - a pair of them would make about the correct length.

Pardon the blurry image - it's getting dark outside!

Hi Keith, is it the gearbox mount spring that alows for some movement?

I dont have a parts book, but what about a steering joint (adjustable drag link), or from behind the snail adjuster on the brake backing plate.

Thanks for the suggestions... the drag link spring is 655861 and I think this is a little small for that...

They could almost be clutch plate springs, a fairly useless spare part... I can't find a diagram of the rear engine mount, and am not familiar enough with the way GM designed these.

The number for the spring does not appear in CCKW,DUKW or Staghound SNLs. Group 1205 deals with Master Cylinder strangely enough.
Group 1205A, no listing.

Just scratched the wax off the pack and the group should read 1203A, and the part (now also without wax) is #477440 - the '#' symbol was confusing - sorry to put you on a false goose chase!
But the part number still doesn't seem to be in a CMP book.
