Set of used factory 914-6 heat exchangers. Heater shells need some repair. Cheaper than a set of headers, and these flow very good. I know of a few 3.0 conversion cars with these working very well on them.
$550 $500 $475 plus actual shipping. Carefully boxed up and ready to ship. Here’s a 3:38 minute video:
