I reckon that seat base might be beyond repair.
But that doesn't mean Leightons won't say differently.
I'd email them a bunch of photos and see what they suggest, and how much it's likely to cost.

Evening Gus,

On subsequent inspection the seat pan also appears to have been fibre-glassed underneath, I don't expect it is going to be worth the effort. New replica seats seem to be available so I'll check them out.

Cheers Zunspec

I seem to remember something about this being posted before. I think yanks have a slightly smaller inch & it all stems from that. I'm sure the other thread to mention it talked about the reason Allison Merlins were shite for a while was following proper UK measurements rather than translating to yanky ones.

Does this have anything to do with the urban myth (?) about the New York prossies' ruler? The one that is calibrated in smaller inches to make the bloke think he's bigger than he is? :lol:
I know a lot of the US measures are quite a bit different from British, certainly their Ton is different (short Ton) and I notice they tend to express body weight in pounds rather than stones/lbs.
I do remember meeting a guy who was working on a Harley for the first time and was confused by his metric spanners not fitting. When I mentioned AF his reply was "wassat mean.....American Fred?" :roll:

Most probably telling folks what they already know, A/F means measured across the flats,so a UNC or UNF bolt is matched to an A/F spanner by the opposite flats on the hexagon head ,where as Whitworth + BSF and what I call Imperial spanners are measured by the Diam of the bolt.
Ain't got me head around Metric yet,but i know 13 mm is handy :lol:

it might be cheaper to get one of these rather than buying a new base to recover?

Their gallon is wrong too i think. They still use the one they stole on the Mayflower but ours changed at some point. I forget who it was on here explaining it all once.

Thanks Dave, thats the route I shall probably take. Lots of other stuff on the Burtons site so thanks for the link also.

Cheers Zunspec

Gus most likely!
When I was an apprentice I worked on a job that had some bizarre (metric) dimensions.......metric inches they was; the drawing office had simply converted the dimensions from feet and inches into miilimetres without any rounding up or down :roll:

Nope, I think it was a yankie member. Gus chimed in later about gallons of ale & so forth.
