Dlock13 Posted July 31, 2008 Share Posted July 31, 2008 Hi all, we have a R400 that has been changed over to a 237 and a 6 speed with Pete air ride and is in really good shape. Matter of fact it was completely restored about 15 years ago and with a lot of projects it never was finished. Originally it was to be a small wrecker, but we were considering putting it together as a large rollback. I also have a 79 DM which also has a 237 and 6 speed with camel back. My question would it be possible to switch the cab and hood and all necessary components from the R400 onto the DM frame? I have lots extra parts in stock and I was wondering if it was possible or not? We have put together some trucks before like the our last project which is a 2003 RD that we morphed into a 306" wb Granite 60 ton wrecker. Any way just wanted some opinions on the subject. Thank you Dave. Quote Link to comment https://www.bigmacktrucks.com/topic/4061-can-you-build-a-r-model-on-a-dm-chassis/ Share on other sites More sharing options...

Thank you Dave.Hi Dave, from what i can gather the DM has 2 different chassis, the 800 has straight thru rails, the 600 has a profile like a B except deeper. The R800 uses the same chassis as a DM800, anyway i dont see why you couldnt centre the cab on any of the chassis. You might just need cab mounts, and i dont know if the R400 cab mounts would do, or if they would mate to a DM chassis. Im from Australia, and we dont have many DM's here and less R400's, im sure there would be somebody in the US that would know better. Regards Jeffro.

David Posted August 1, 2008 Share Posted August 1, 2008 Check the frame width. Some trucks are 33" and some are 34". Quote Link to comment https://www.bigmacktrucks.com/topic/4061-can-you-build-a-r-model-on-a-dm-chassis/#findComment-20984 Share on other sites More sharing options...
