Hi all,

I am trying to find out the diameter and pitch of the small machine bolts that hold on the glove box lock mechanism and the center console. Both appear to be 4MM but I have tried 4MM at .7 pitch available at Home depot and Ace hardware (thrifty now) (both in the U.S.) but they seem awfully hard to turn after I get them screwed in very far. Both of these places only sell 4MM in .7 pitch but I notice my die set has both .7 and .75 pitches. A P.O. had wood screws in place of some of the screws so the threads are chewed up a bit. I tried to put a metric 4MM die in the holes, both a .7 and a .75 pitch but neither turn by hand easily. Anyone know if there is a typical pitch used in the interior of an early Z or what they actually are?

Thanks!

Mike

The console bolts (the three in the rear that go in vertically) are 5x0.8, the two glove box lock bolts are 4x0.7mm. You will need to run that tap through with some lube and clean them up, thats all. Hopefully they aren't beyond repair. Wood screws, ouch.....

zKars,

Thank you for the information and reminding me about the lube. I imagine the threads are basically good otherwise I would not have been able to get the bolts screwed in as far as I did. While previous owners have caused me some work I am grateful for their efforts at preserving the car as it must have spent most of its life in a garage based on its current rust free condition.
