1973 911T Outer seat slide rail bolt removal

[Toddah]

Can someone help me find the special Allen wrench that has the little centering pin on it? Don't really know what to call the wrench.

Probably a security type socket screw. They make Allen and Torx keys for these. The Torx is most common so look closely at the pattern and magnify if necessary so nothing gets stripped.

Thanks for the reply.
I am firmiler with the security fastener in Torx and allen but they have the protruding pin inside the fastener head.
This fastener has a 5mm Allen socket head cap screw but instead of the tit it has a hole at the bottom where the Allen wrench with the tit fits into. So just to opposite of the security fasteners you mentioned

All my socket screws were replaced with hex bolts, not sure if they’re any easier to remove vs. sockets due to that design and tight quarters.
Any hoot, there are specialty allen socket screws with a hole drilled through the center for oiling purposes, it shouldn’t require any special tool.
That said - I researched and found this - A Pilot End or Tip allen key, hopefully you have a local source shipping from M-C is costly.
