subject line 'bout sums it up. I'm getting nothing on my dash, everything worked fine before the 700 to T-5 swap. There's a slow leak where the cable screws into the case so I'm pretty sure the O-ring is shot, plus there's a little play where the drive cable slips in (is that the bullet piece mentioned in other threads?). The tranny case numbers come back showing it actually came off a Mustang but that it is from the WC-era ('89 I think, don't remember). I'd like to switch to something I'd never have to switch from, can you calibrate an electric speedo with out changing gears? like to accomodate tire change, rear-end changes, etc? Any ideas on how to fix the one I have?

Thanks!
