This area is for ebay, Craigslist, GSA, Government Liquication or other auctions. It should include auctions for WWII trucks, parts, trailers, and directly related equipment and accessories, for CCKW, Chevrolet 1.5 ton, US-6, M5-6, DUKW, and WWII trucks larger than 2.5 ton vehicles only.
I was looking at bidding on this manifold and taking a chance that it would fit a 270 (always hard to find in the UK).
It turns out the guy will not ship to the UK, so solves the problem.
If anybody over in the US wants to take the risk for $75 ?
