1973 Volvo 145 B20F Header?
 

I have been trying to find a header for my 1973 Volvo 145 B20F and have had no luck. Can anyone tell me where I might find one or if another header works off a different vehicle on the 145? Or something? I have a crack in mine and need to get it replaced.

Hmmm...you're in Washington? Lots of 140's still around on the west coast. Assuming your 73 is DJet injected, your header is a thick base plate version to match the intake manifold. IPDusa.com sells them, a bit pricey though. Skandix.com has them. Occasionally eBay has them but there's no real way to know how rusty they are until too late.
