Butchee Posted October 25, 2019 Share Posted October 25, 2019 Hi Gents I have a 1989 RD688 and want a cab. I have some good doors. Would anyone know what cabs will interchange and what years ? ? It looks like the rd690's cabs are the same and most all the RD years look the same..to me . Thanks Quote Link to comment https://www.bigmacktrucks.com/topic/59527-what-rd-cabs-will-interchange/ Share on other sites More sharing options...

Thanks The R cab is primarily unchanged, with the exception of adding 3 inches to the back side of the cab in the early 70s. Might be minor roofline changes, but that should be about it.
