Mechanical speedo on a 700r
Installed a 700r/ls1 in an old truck. 700r Tailshaft has drivers side elec. speedo output screwed onto a male threaded stub- which appears to be same for hooking up a mechanical speedo. The center of the male stub has the square center of a plastic gear meshing with the tranny gear inside.
Anyone know if you can run a mechanical speedo off of this fitting of an 700r?
Thanks for the assistance.
