70 upper shifter boot and screws

[Bill L.]

Does it matter whether the leather seam is on the driver or passenger side?

What size phillips heads screws attach to the plate. The ones that are there now seem like the head is too big.

Thanks, Bill

I think you will find that the base of the boot is not symmetrical and will fit into the shifter plate in only one orientation (unless you "force" it to fit in the wrong orientation).

As far as the screws go, they were a #8-18 self-tapping screw of 1/2" length. They had an oval phillips head with countersink-type base. The unusual thing about them is that while they were #8 size, they had a head the standard size of #6 screws.

By the way, while they did have a reduced size head and were countersunk, they did not really fit flush with the shifter plate---they stuck out a little even when fully seated. I don't think that the countersink in the shifter plate was really large enough to fully accommodate the countersink in the screw.

Thanks Joe,

I am assuming a phosphate finish.

I thought the same regarding the shape. The one on the car has the seam one way and if I install the nos GM boot according to the shape the seam will face opposite of existing boot.

The screws there are wrong for sure.

I would describe the screws as having a phosphate finish.

I don't usually have much to do with Corvette interiors, but I seem to remember when we did the Judging Manual in 1993 we specified which side the seam of the boot was on original boots. While I can't recall why we did that, I would wager there was a good reason. You might want to check the TIM&JG -- that call out may have survived the subsequent revisions.

Hi Terry,

You are correct. The manual says as much.

Do the screws stick out some or are they relatively flush? The holes in the plate do not appear to be beveled at all.


Thanks!

Re: 70 upper shifter boot and screws

If I remember correctlty the screws are countersunk with an "oval" head theat means it has a slight bump to it and that is what sticks out when installed. I would have thought they would have had a flat head.

The screw heads "stick out". Any countersink in the plate screw holes is very minor and most of the beveled (countersunk) portion of the screws is exposed.

Thanks!

Think I have found the correct screws. I believe the OD of the head is .27" (#6).

Just wish they did not stick out but that is the way GM did it.

This was a "design feature" that I questioned the very day I was delivered my brand new 1969 Corvette.
