You want to find a used one!  VW shops often have them for sale, and folks who do conversions may have them.  Also check The Samba, they pop up there every once in a while.   I believe it was used on most VWs that had Digifant EFI in that era.

Does anybody know where I can find this?
Or know if anybody repairs this? I’m outside of Philly.
GoWesty is sold out.
