Gear Venders Overdrive ?

Hi guys and gals. New to this but I'm gonna give it a try. Sorry I'm not really a computer guy. I'm going to ask a question as I'm looking for past and present experience with Gear Vender Overdrives. Just wondering if anyone has used them or are using them and what sort of experience you've had. I'm considering using one on my 68 Dart GTS 340,4-speed,3:55 rear,24" tires. This is a driver and with gas prices the way they are, I thought an o/d would be the way to go, as I would like to run much lower grs, maybe even as low as 4:56. Thanks.
