All this information has long been known and I've posted pix and descriptions on the web though I can't recall where.
In the case of the seat, you will also see the seat perches that mount at the rear shock towers have ALSO been moved back by the same amount. Only the rear Dzus tab has not been moved. In that case the fender dzus hole was modified instead.

I went through this exercise a few years ago while trying to come up with a plan to turn my 63 Atlas into a small tank 62 88SS. My freinds manxman, that I was working on, was invaluable for genuine information and showed me how many parts I would have to modify or make. I would modify a seat base but not butcher a good fender since tht bike will eventually become a 650SS then eventually revert to a "combat" Atlas hot rod. Some day it might go back to pure stock too.
I have a '62 bitsa with a later, right side filler, large tank and the corresponding rear fender. I also have a small tank sitting on the shelf. Since I don't want to butcher the fender I have always wondered about mounting the small tank and extending a stock seat with hard foam. I know the result wouldn't be "concours" but it would allow for use of the small tank without any more butchery than reworking the foam on a standard seat. Any thoughts?

By small, I suppose you mean the 2 1/2 gallon size. This was the tank fitted to my '62 Atlas, and that on my '63 Atlas.

The early versions had the filler cap left of center ..... This was moved right of center in later (post 64?) years.

They can be found on eBay occasionally, and bring a high price if in good shape.

I too, like the look of the 2 1/2 gal. tank, but it means frequent fuel stops on a long run.

Slick

At 50 to gallon you do around 130 miles then a stop of a top up by then you need a toilet and a coffee and a Berger before setting off again even in the USA there must be a garage with in a 100 miles or so

Its probably helpfull to realise that the Small tank was not seen on Uk bikes back in the day ,may have been an option but was not seen as a proper big bike tank by uk Buyers . If anything Uk riders wanted 5 gallon tanks ,which they got by buying glass tanks from Dunstall etc.
