Can anyone send me a picture of the bottom of an original 1960 / 62 A10 seat? I have a new reproduction seat that will not mount in the rear using the original rear brackets. If I make longer brackets, the seat will sit up to high. I also have a problem with the description Bacon gives in his restoration guide saying "the two-level aspect became more accentuated". Isn't this incorrect? I thought the '60-'62 seat was flatter. Can anyone advise me on this. This repro seat is fairly flat in the rear - shouldn't if be indented to follow the top curve of the fender?
Thanks
Sam

Hi Sam,
What brand is the seat?
Most are wrong shape and poorly made / fitting
The best seats I have seen are made by RK Leighton in UK

The early seats were thicker under the riders bum, or rather the base followed the frame and the mudguard shape. The rear bracket was a one piece that bolted to the top of the mudguard.

The later type was flatter, and the mounting was 2x L shaped tabs which bolted to the side of the mudguard.

I can't see why you can't use an earlier seat on a later frame or vise Versa as long as you match the brackets to the correct seat...

One thing to note however is I have seen these mudguards fitted without the rubbers between the guard and the bracket, or the wrong thickness used. But therear guard is often cocked up too high, this would also stop the seat mounting correctly.

The seat I purchased is a P&P. It definitely doesn't fit. I just ordered a Leighton seat after seeing a picture of the base. I hope I don't bleed to bad on it.
Thanks for the replys.

Hi,
Do not forget to fit the rubber supports that go under the mid seat area
They fit into the vertically threaded frame holes

Kev - thanks for the pictures. I bent way over and bought a Leighton seat - it fits perfectly. I do have a few questions though - what are the two extra holes for behind the rear mounts?
Also ls the handrail an accessory or was it stock on all bikes? The parts book list the handrail on the same accessories page with the crash bars and carrier. Yours is the 2nd bike I've seen with this rear bar on it.
Another problem has popped up concerning the pipes and mufflers. The right muffler has to be 1/2" closer to the rear rim than the left to clear the kick starter (by about 3/16th "). It looks bad to me - is this standard British B/S?
John - I'm on it about the two seat rubbers above the vertically threaded holes in the frame. What about the hole towards the rear of the seat pan - is there a rubber that fits in this rear center hold in the seat base to help support the passenger portion of the seat?
Many thanks for your reply's
Sam
