Gear vendors overdrive unit. Currently in a 79 dually truck. Performs flawlessly. Rated up to 1200 HP. This one comes with the SM465 adapter, but you can get an adapter to fit nearly any trans or transfer case at
www.gearvendors.com. Still in the truck so you can drive it if you are close by. Includes all wiring and electronic components to install. Driveshaft is also for sale if you plan on using in a long bed truck behind the SM465. $1500 plus $75 to crate and ship anywhere in the lower 48. Or buy the whole truck and drive it home with a strong rebuilt 454 and rebuilt front suspension for $3200. Thanks, Sharpie
