Get/borrow a wideband and learn how to do it, that's what I did with my Datsun when I couldn't find anyone around here. Pretty easy because of little temp and no elevation change. National carburetor off of Belfort is amazing though, they've got everything you could ever need parts-wise. Check with them, maybe something's changed and they can recommend you somebody.

Third on Driveline, they built my driveshaft and did a great job for a more than reasonable price.
