I have a set of Sanderson CS13 S-10 Small Block Chevy conversion headers. 1 3/4" primary tube and 3" collector. Brand new high temperature gray powder coating. They are 2wd headers but I used them on my 4wd truck and only had to trim the top corner of the drivers side shock mount. I used them for 2 Saturdays at Silver lake before I broke my truck and I am facing reality, this truck will never go back together. They do fit fairly tight to the block so they could be used for other small block applications.
