I'll trade you... A DII 4.0 plenum chamber and intake manifold that's in fair condition? Hell, I'll toss in a set of ugly but functional valve covers, as well. The stuff needs hardware, but it's not broken.
I bought it all to restore and button up my engine while the rest was being powder coated, but I couldn't bring myself to put non-original bits on her, even temporarily. I'm very particular about that sort of thing.
OR:
You give me that thing, plus 300 bucks, and I'll ship you an unused Magnaflow stainless steel Y pipe and cats (built for the DII, by Magnaflow) that needs a bit of fiddling. Fits right, it just needs an 02 bung chased. I couldn't be bothered to do it, so I just bought another one. I'd intended to return this, but I'll sell/trade it.
OR:
You give me that thing, your eternal soul (legal contract required, as well as a certificate of authenticity by a cleric of any major religion), and 3,000 bucks, and I'll trade you a 1-off all new 300 amp alternator with a spanking new custom cast chassis and Weatherpack connections.
Cheers,
Kennith
