  1. That makes sense with the firewall and would explain the difference in the B & W photographs. Was the same done to the fenders? They sprayed the whole fender the body colour and then only buffed the outside?
  2. I found some information in relation to shimming body mounts in convertibles which may be useful to you: "Convertible models are to be shimmed using hard shims except for #6 and #7 center body bolts which use the closed car soft body shims. When shimming, the top should be loosened and when lowering the top , care should be taken to see that the top pilots of the windshield with no excessive strain." My 40 super has 22 mounting locations. Between the body and frame was a square piece of rubber that was about half an inch thick and soft. Under the frame was a thicker and harder round rubber I think acted like an insulation washer against the bolt. A friend gave me a sheet of rubber built for absorbing vibrations in machinery mounts. I will use that for the square pieces between body and frame. On other forums I've seen the word "hockey pucks" used in relation to body mounts. I'm not sure if they actually used hockey pucks as a substitute or just called them that because they are similar size and shape. I haven't found anything suitable for the round ones yet and I'm not prepared to pay the price for Cars/Bob's body mounts.
  3. Hi Ken, I haven't been able to find any documentation on this. From 1940 production photos this is my observation: Vertical section of firewall appears to be a different colour from both the chassis and body colour. This extends to the angled section were the pedals are. I can't tell what the colour is. The flat section on top is same as body colour. Radiator housing same colour as firewall. Stoneshield and under fenders appears same as colour body. The body floor was sprayed with a sound insulation paint (this is documented but it's not clear to me if they are talking outside or inside the body. I know the outer side of the underseat heaters were sprayed with the sound deadening material. Matt
  4. You can buy a reproduction copy of 1940 buick facts from BHA which is what I did. The book must have been printed after the seamless filters started to be used.
  5. In assembly line production photos of early 40 and 41 Buicks it can be seen when there was a seem the filter was black and when there was no seem it was aluminium. It's possible the replacement filters were black
  6. I placed an order in December a didn't hear anything. Same thing about the email bouncing back but I managed to get in contact with David Landow and the order was shipped DLandow@LandowCo.com
  7. You own a copy of 1940 service bulletin? See page 139
  8. The correct colour is aluminium paint. As stated in "Buick Facts 1940" and "1940 Buick Parts and Service Bulletin" The first filters were black but it's unlikely you'd have one of them as many were replaced due to leaking at a bottom seam. The seam was eliminated in the second edition of filters.
  9. Is there a misconception of calling it "engine turning"? The term derives from the Rose Engine machine or that it started off on the engine cowls of aeroplanes? Anyone heard the term "spottng" before? I hadn't until I saw this webpage: https://www.circuitousroot.com/artifice/machine-shop/surface-finishing/engine-turning-vs-spotting/index.html
  10. I believe it is leather, I have it on my car but it's deteriorated so I am going to replace it with rubber tube and paint brown. As others have already said main function stop metal hitting metal during operation of lever.
  11. Found these 1940 photographs of an Australian bodied Buick. I wonder if they done locally or imported. I can see its s different radio panel
  12. Not that Doug probably told you but when he says "imprint", does that include grooves being formed into the metal surface. With my own panel I could not see what looks like to be grooves scratched into the surface by eye, it was only by zooming in on the photo I took that they became apparent. I'm thinking of borrowing or buying a dial test indicator to run across the surface.
  13. I haven't seen the details of it so I'll check it out
  14. Yes that's possible. Or at some point somebody was providing replacement decals. Once the lacquer protection deteriorated the bare metal rust quickly and as I demonstrated, it doesn't take much sanding for the finely machined swirls to be removed before the rust is.
  15. Zoomed in again. I'm pretty amazed at the detail from a phone camera. Those circle marks aren't seen to the naked eye
