Found this on craigslist. Starter looks interesting, maybe Jay has the brochure.http://sacramento.craigslist.org/cto/5961100243.html
Gray and Davis
This setup is too cool!
Efficient? Prob'ly not.
Cool factor with the hood open or for a demonstration? Yup.
95% free starts is also too cool !
i have one of those g&d units for my 15 form-truck only mine is a single unit . charley
I have the starter itself for one of these Gray & Davis setups. It turns with 6 volts applied. $75 plus shipping will buy it.
If anyone is interested, send me a pm. I might not check back here.
