Re: striker pin

All------


Well, I did a little more research and I learned something. The drive style used for these strikers that APPEARS like tork is actually a drive style known as RIBE or POLYDRIVE. It uses a 6 corner "star" pattern which is similar to but not the same as torx. Plus, it's an english size system, not metric. While there are specific driver bits available for RIBE or POLYDRIVE fasteners, regular, english size allen head tools will work just fine. In the case of the Corvette strikers, a 1/4" allen wrench fits perfectly.

I still don't know why it was used or why the NOS fasteners of the 7660559 and 8770193 I have are clearly hex drive only whereas examples seen on cars are RIBE. It may be that these strikers were manufactured by multiple suppliers and the drive style was optional on the GM specs since the same tools could be used for drivers with either type drive socket.

Re: striker pin

Joe,

My 1970 (Jan 29 on the trim tag) has hex drive. I noticed the Star drive on the February cars. Your 1969 striker is a surprise to me. I guess we are all learning something today.

I still haven't had a chance to take a look at the 1969 or 1970 AIMs.

The 1968 through 1970 AIM's all specify the GM #7660559 striker. That's the one shown in several of my photos with the hex drive.

All I can figure is that either there was another striker used that was not specified in the AIM's or shown in the P&A Catalogs OR the striker specs allowed for it to be supplied with either the hex drive or polydrive. I'm kind of thinking now that it was the latter. If so, either drive would be "correct".

I had a friend check his early-build, original-owner 1969. His car has the hex drive type striker.
