Size of screws holding 1/18 to the base

[HomerS]

I've only taken a couple of the cars out of boxes and put them in a case, but I tossed the screws.  Recently I bought two Ertl AMX's still in the box but they were not mounted.  I have some screws from cannibalized diecasts that fit diameter wise but certainly not long enough.  

Anyone have some they can measure or give me a rough guestimate of the length?

Unless you can get some from another Ertl AMX it'll be a real BLAH_BLAH_BLAH_BLAH shoot to find the right ones. Over they years Ertl used many, many different screws to hold the cars to the bases. Different lengths, different threading, some Phillips head, some slotted head, there's no standardization whatsoever. The best way to figure what length you need is to put the car on the base, then put something up from the bottom of the base into the screw hole in the car (toothpick, tiny screwdriver, anything skinny) and measure the depth of the hole. Hope this helps.

I stopped at the local RC Shop yesterday after the Cincinnati Auto Replicas show and the young man was extremely helpful but didn't have the size I needed.   Went to Lowe's this morning (best bet to get a retiree who actually makes the effort to help you!) and we found ones that worked......#4 x 3/4.
