yes you can rool it back but you have to go slow but really it is not worth it i did mine about 1000 took for ever my car is at 315 well the shell


as for disconnecting it that easy as pie

just pop the cluster out any one can do it as shown above


this si how you do it wiht out breaking any thing

there will be green cup aka the speed cable
what you do is un clip it from the dash it self by poping it ouit

then take tape and cover the speedo spine so no dirt get's in there same wiht the dash part but don't take that gears out or you will get bad speedo gitter

then pop it back on make sure all the wireing clips int he back don't get in the way and pop her in

as for reinstal it can be pain to line it up i cna do it in secounds now befro it took me a good 5 mins to aline it and stuff

or even easyer way is to jack up the car wiht my jack look o the trans it self and find the speedo cable and just looen it and it will not work no more that way is the easist and the fastest

call me tomorow if you have any prob's
