VIEWING MULTIPLE TOPICS ON SCREEN: You can choose to see more than 10 Topics at a time ... Log In and choose "Preferences" from the top bar on the Forum page. Scroll down and Change the "Default Topics Returned" parameter to 25 or 50, and save the changes. Since this setting is stored in your browser 'cookies' (if enabled), it seems to use that stored value even if you are not logged in. So, if you use a PC that you haven't logged into the forum from, the setting still seem to remain at the default.
EXTERNAL PHOTO LINKS ON FORUM: You can still use external photo links in your posts on the new forum. They follow the rules of any link in that they have to have the URL link qualified down to the full image file name (example: .jpg). The links will open in a new browser window, the same as an uploaded image attached to a post. Since an image attachment to any post does not display inline with the post, the results are the same. You can use multiple external links within a post. This link is from photos on a site from Don Clink's 'Deuce@75' albums:

Using links from photo sites such as Photobucket can help in "size" issue with uploaded attachment files. For best viewing in web browsers, photos should be around the 800x600 pixel range, and probably not more than 1024x768. Most cameras today store HUGE jpg image files, as the default settings are in the 7, 8, 10, and 12Mb image sizes. The image files that are then attached are very large, and the browser can't display the full image size without using the scroll bars. Use the re-sizing functions of your photo editing software to reduce the image to 800x600, which reduces the file sixe and the image load time in the browser. Don uses Google's free Picassa3 software, which is an excellent photo management product. All of the photo albums of the Deuce, Grand National, and Auburn that are links on the NORG site were built using Picassa's web creation functions. And it's free? (THANKS to Don Clink for the info!)

Who has a correct reproduction fan belt with raised script part # for a 1940 ford 85hp std coupe?
Thanks Tom.

Absolutely NO ONE reproduces a correct fan belt. The screen printed ones you most often see are incorrect as 1) the original belts had the numbers, etc. molded upon the belt, not painted and 2) the repop belts are too narrow thus ride in the pulleys too shallow.
You will have to search for a correct belt. On occasion they come up for sale. Expect $100+ for NOS.
1940 Fords built prior to early June, 1940 used belt #78-8620-A. After the early part of June the part number changed to 78-8620-C.
The "C" belt is a bit shorter to accommodate the smaller generator pulley that was placed into production at the beginning of June 1940.
VERY often you will see the incorrect pulleys on restored 1940 Fords. Be aware that the first design was 3 11/16" diameter and used until the beginning of June, 1940. The smaller (more easily found) pulley was 3 3/16" diameter and wasn't placed into production until June, 1940.
Hope this helps.

What is a 78-8620-C3 for? I have one N.O.S. still in the FoMoco cardboard wrapper.

C3 is simply a revision of 'C'. Length and width are no doubt the same. It may be possible it was a change in construction, etc.
I'd be interested in that belt if it is for sale.

The wide vee belts depend on the angle of the sides to prevent slipping, and even if the length is correct, the angles may not be. If you try to overcome that problem by tightening the belt, it is likely that the water pump bushings will be damaged. Correct belts, particularly those with the "script" markings, tend to be expensive, and NOS belts may be very old and hardened by exposure to ozone. Many report that the "correct" belts don't fit. We buy ours from a local electric motor shop that has a big selection of lengths and pitches.

The "A" belt SHOULD fit on a stock '40 with the 85HP. The "B" belt was for 1939 with an aluminum valve chamber cover. Those (B belts) will NOT fit a cast iron cover.

Good to hear the repop belts (A type) fit the large pulley.
I never understood why it is apparently so difficult to make the hose clamps correctly.
They are as you suggest too small. I have a limited quantity of NOS clamps and when compared are definitely a larger diameter.
