RobSR Posted April 25, 2017 Share Posted April 25, 2017 Hi all, Im guessing some of you on here have a gearbox out the car..could you do me a favour and measure the pitch and thread of where the speedo cable screws in please. Im trying to get some proper speedo converters made as there are many people after them and i need to know the measurements. Ill have my box out in a month or so, so can do it then, but it would be nice to get them done before! Thanks, Quote Link to post Share on other sites
gorganl2000 Posted April 25, 2017 Share Posted April 25, 2017 hey Robsri actually have a disassembled gearbox in my store room,,,very close to hand...,but what tools would i need to determine tread pitch/size?....as i doubt i have such readily available, but could ask around and see digital caliper?---i have thata die/tap? ---i dont have those Quote Link to post Share on other sites

gorganl2000 Posted April 26, 2017 Share Posted April 26, 2017 (edited) well...the diameter measured approximately 21.7mm tread pitch is either 1.50mm or 1.25mm....its kind of difficult to tell with the digital caliper i hope the others can shed some accurate light for you Edited April 26, 2017 by gorganl2000 Quote Link to post Share on other sites
