Who likes playing the game \"matching\" for overdrives? I have an NV4500 5spd that will soon be mated to an NP205. I have a Gear Vendors overdrive that is mounted behind a 205. I can't make up my mind on what vehicle to match them to... a 1981 Crew cab with a current 454/465/205 and 35" BFGs with 4.10 gears (this tows alot). a 1981 Suburban with a current 454/465/205 and 35" BFGs with 4.10 gears but will be getting 4.56's soon. The adapter between the tranny and T-case is cracked, so one or both must be pulled regardless. then theres the red truck... a '78 3/4 ton 4x4 that will have a 350/465/205 and 3.73 gears turning little 31's. I was going to put the Gear Vendors in this truck when I put it together, but I may not and just run it w/out an OD. Or put the Gear Vendors on it, and leave the Crew Cab as it is. Based on these facts, what vehicle would you match the NV4500 to, and what would you match the Gear Vendors OD to?
