Best way to mount Manx seat to Slimline frame?

What's the story of the one you're putting the seat on?

The mounting looks pretty good to me, by the way. Norton closed up their race shop shortly after the Slimline came out, so there were very few Slimline bikes from the factory that the Manx seat ever made it on. Yours looks as good as any of them.

Thanks. This one is a modern aftermarket seat made to fit the Slimline frame. An inch or so narrower at the front than Wideline seat. Yes it came up looking pretty good in the end. I left the two "wings" sticking out the back of the flat plate so they can be the anchor point for a small battery carrier in the hump in future, maybe.

Kind of a long story on this one too. I built it in about 3 weeks flat in about 1989 or so when I lived in Montana. Basically it was my spare Sportster engine and a spare Atlas frame from a pile of parts I bought for my Atlas from an old farmer. So of course the two had to go together. Just fooling around one day I lay the Sporty engine on its side on the floor and wangled the frame down over the engine. Was a tight fit around the rocker boxes and I had to jump on the frame to spring the bottom tubes over the oil pump but it popped right in there. So I stood it up and made mock up engine plates in cardboard after chocking the engine up with bits of wood to get it sitting straight and in line with where I figured the back sprocket would sit next to the swingarm. Made up the engine plates from bits of flat steel and some 2" steel angle at the back on night shift at my job in maintenance at the local hospital. Bolted it all up and it fit. I had Trident T150 with blown engine in the shed so robbed the rear wheel and front end off that. A quick wiring job and slapped an Atlas tank and seat on it, some BSA fenders and I rode it around for a couple of years. Then the front end went back on the Trident and life kind of got in the way so the Snortster sat unused in my shed for the next 30 years or so. So figured it was time to get the old girl up and running and get that Manx tank and seat that I always wanted. Waiting for the tank to arrive now from Tab Classics in UK. Then still a million little details to sort out but getting there.

If it's only a million, you're ahead of the game! Having all that torque in that bike might just be pretty dang fun.

That last pic is KOOL !

Yes I will be a grand master of making brackets by the time I finish. Everything almost fits, but nothing quite fits. Yes the Harley Sportster torque is a hoot in such a light, short bike. Bit like putting a Chevrolet V8 in an MG sports car. You crack the throttle and that thing pulls like a steam train.
