I have been tinkering with a 1952 1/2 ton 3100 for years and I have just added a 1987 chevy 1/2 ton long bedto the garage. I have a couple questions about the NEW truck. It is a R-10, per the registration. What is the difference between a R-10 and a C-10? How can I tell if mune has a large hump or small hump? is there a measurement? thanks
In 1987 Chevy changed the Line description and Chassis type. C10/ 2WD 1981-86 K10/ 4WD 1981-86 R10/ 2WD 1987-89 V10/ 4WD 1987-89 http://www.lmctruck.com/icatalog/cc/full.aspx?Page=12 The tunnel hieght usually follows. 2WD low tunnel 4WD high tunnel When I changed cabs I had to installed a high tunnel to clear the transfer.
