Why is everyone obssessing over K's these days? They aren't that great. :doh:
You're going to love the wiring it will need, and the swap kit would probably cost more then the 84-87/B-series kits.
Don't the K's have F/H style cable shifters? That would be another bitchy part.
Oh, yeah, and the whole low supply/high demand part. K's aren't cheap.
