Brand new set of Doug Thorley THY-324Y-C LS swap headers for 2wd and 4wd 67-72 GM Trucks (C10, K10, K5, etc.). Bought and mounted on my K5 but went in a different direction, so my loss is your gain. They have been mounted per the pictures, but are absolutely brand new. Bolted in nicely, but were almost touch my firewall. Didn't want to move my engine and trans of dent my firewall at this point. Fit great, but my motor mounts are just slightly too high. These cost $650 new. I'm asking $450 plus shipping. Still have all hardware, gaskets, collectors, and instructions.
THY-324Y-C Headers:
- Made in the USA with limited lifetime warranty
- Extra thick 14GA tubing and 3/8 inch thick flanges
- 1 5/8" primaries with 3" collectors with 2.5" adapters
- Ceramic coated inside and out
