Was your Hydra-Matic floor panel countersunk, too?
I doubt if I bagged and tagged my original floor-panel screws, but I will look.

But these are the exact replacement screws to the original screws in my 1950, 3600 w/4sp. The cover is not counter sunk for a flat head screw: http://www.pbase.com/dennygraham/image/159800571dg

I don't own any Chevs, but it appears that GMC and Chev used the same screws. | | | | | Joined: Aug 2001 Posts: 1,299 'Bolter | | 'Bolter Joined: Aug 2001 Posts: 1,299 | Denny, can you take a look at your 54 for me? Thanks, G.H.
I think they may have changed that year...still makes me wrong as he was asking about a 52 but makes me at least feel like I am not losing my mind. | | | | | Joined: Sep 2001 Posts: 29,269 Bubba - Curmudgeon | | Bubba - Curmudgeon Joined: Sep 2001 Posts: 29,269 | I just now got back from a long day on my last week at work.
Do you all now think the 1954 transmission covers were different from earlier transmission covers (I have 1954 3-speed, 4-speed, and Hydra-Matic covers). Should I look tomorrow to see if they had slotted-head "flat-bottom/base" screws or counter-sunk screws?
Did people confirm that 47-53 3-speed & 4-speed covers used counter-sunk screws? And, were they clutch-head?
As usual, I am confused.

Steve | | | | | Joined: Oct 2006 Posts: 9,671 'Bolter | | 'Bolter Joined: Oct 2006 Posts: 9,671 | Must be confusion with what you're gonna do when you don't have to punch the clock next week Tim, congrats by the way. I think what I can take away from this is as Steve posted, not counter sunk up to '53, all truss head clutch drive then '54-'55 were flat head on the floor and truss head on the toe board, both clutch drive. All of these are carried by .Restoration Specialties & Supply Inc. http://www.restorationspecialties.com/ Seems pretty clear unless I'm missing something. dg

This thread made me do some checking and while my slot head memory was correct the flat head machine screw wasn't. It seems that slotted oval head is more accurate for the OEM screws on my '38.

Neither Chevs of the 40s or Jim carter have a listing for '37.

All my other 3-speed and 4-speed covers are flat (not counter-sunk) but I do not know if they were 1954 or earlier or after-market.
