there is a guy in florida that rebuilds them. we sent him one out of our 2510, when he got it he called us and told us it was an aftermarket one. he put than original style can on the back side and original style face and needle and fixed anything else that needed attention. also sent him the tach out of our 730 a year or 2 before the 2510. relatively quick turn around, week and a half to 2 weeks with mailing and all.
