I must admit that I have never taken an Angle drive to bits. I know they have a rather high failure rate, I have needed 2 over the years. I also know that one of the American clubs sells a "beefed up" one. Speedograph are working on replacement. I just assumed that the internal bits were plastic, wrongly, it seems. Apologies for any confusion caused. I'm still looking for a spare 85mph speedo head..working of not, condition unimportant. Has anybody got one they could send me? I can then try and get an "Exchange" service for a 140 MPH one...work out costs, asses quality etc. Chris Parnham Hon Sec.

He says using much > stronger metal gears could cause other problems Chris, I find this very interesting. Every Delorean angle drive I've rebuilt, and it's been quite a few, has had metal gears in it. I've never taken a Delorean angle drive apart that has had plastic gears inside. Marty
