melliott Posted May 28, 2015 Share Posted May 28, 2015 My GT6 mk3 (1973) non-rotoflex has a J type O/D gearbox, is this correct or would it have had a D type fitted when new?The gearbox number starts with GR, what does this relate to?ThanksME Quote Link to comment Share on other sites More sharing options...
Clive Posted May 28, 2015 Share Posted May 28, 2015 All GT6 had d type. But the J type with the 3 rail box was fitted to early dolomite 1850's, and is a bit stronger. But same length.GR means it was a factory recon box at some point (I think!) Quote Link to comment Share on other sites More sharing options...
WIMPUS Posted May 28, 2015 Share Posted May 28, 2015 On the Rimmers site i found this : 'Original factory exchange reconditioned units were numbered with the prefix GR and a suffix of /7, and can be identified by these markings' http://www.rimmerbros.co.uk/Item--i-GRID600080#sthash.22AP7rUZ.dpuf Quote Link to comment Share on other sites More sharing options...
timireson Posted May 28, 2015 Share Posted May 28, 2015 Mike papworth told me it stands for general recondition at factory usually under warrantyTim. Quote Link to comment Share on other sites More sharing options...

Nick Jones Posted May 28, 2015 Share Posted May 28, 2015 There are those who claim that very late GT6 Mk3 were fitted with J-type OD from the factory. They do turn up in the 'States apparently and they didn't have the 1850 Dolly to pinch them from.....Nick Quote Link to comment Share on other sites More sharing options...
