I'll send you a 2.1 distributor with a brand new Hall Sender installed....
you put it in your van..
and if it's fixed permanently ..
I'll accept the Lancia Scorpion as payment.

or maybe  trade a vanagon . ? ..
I have 11 and don't think I need that many.

Olympia Wa ..rather a damp  ( rust promoting ) climate for a rare car
like that.
I have a very dry climate location for it.
