Can anyone tell me what size the head of them three bolts are that hold the TFI on the distributor? I see it needs a very thin wall socket but I don't know which size to start grinding on.
Thanks

Just did it on my '91. 7/32 deep socket.

 

I bought a spare at the local auto parts store and got a special tool there at the same time to remove the nuts for about 4 bucks.

 

Thanks, I figured it was an odd size.

 

Oh, almost forgot... I did have to remove the distributer to get to the nuts. Be careful to mark the rotor position before you do it so that you can get it back in the correct position and don't screw up the timing.

The socket at Autozone was a little more than a buck.
