im getting reddy to start a 5 speed swap

Considered that, but from the Chevy cables I remember (haven't dealt with them in 20+ years) they thread onto a mechanical interface at the transmission, so the cable thing wouldn't work. I'll measure the ID of the S10 as well as the Mustang....who knows, might get lucky.

I'd call these guys and see if they have one available: http://www.fortesparts.com/product_info.php?products_id=210

(or if the one in the link will work)

I did the S10 tailshaft conversion on my T5. I heard that if you get a tailshaft from and older S10 with a mechanical speedo (which mine is not), then all that needs done is to relocate the drive gear for the speedo on the mainshaft and stick the Ford VSS/cable end in there. Otherwise, major fab/ TIG work is needed to get a speedo with the electrical speedo'd tailshaft housing.
