Rw Info

Came across an RW today for sale. VIN plate was missing on the door. VIN # on the frame is 1M2V121C2C4001201 best I could tell. There was a lot of paint on the frame and I didn't want to take my knife out and rake the paint off with the owner standing there. Owner says the truck is a 1982 but doesn't know the model. Going by just the VIN can anyone give me any further info on this unit?

I hope this will help. The 4 in the vin must be an A, 4 is not an option in that location. This position is for the plant of origin.

That number doesn't come up but 1M2V121C2CM001201 does. Says its an RWS721LST. Build Date 4/8/82. Built with an EM9 400, TRXL1070A transmission, Mack 92/93 series differentials with 5.32 ratio (looks like automatic power divider, no lockout), FAW537C Steer axle, looks like axle mounted steering gear, 3 leaf front springs, and Neway rear air ride suspension.

Thanks for the info. Truck has an EM9 400 acording to the ID plate on the valve cover. Tranny is now a T2090 which raised concerns with me because I didn't think the 20 series were in production in 1982. Suspension is still Neway air but the rears are now a 4:17 ratio. The cab is very rusty in all the usual places for the non galvanized cabs, rockers, corners, drip rail. The truck still looks nice except for the rust. If I can get it bought for the right price it might make a nice piece.
