Honda-SOHC

We have a 78 F1 model and need a new tank, does a K model fit?
Thanks

OK, the project starts.
The last time I owned a Honda it was a CB175 (twin carb) back in the 70"s great fun and fond memories.
Now somewhat older but with my son we've just bought a 1978 CB750F1 - it's already had some work done and seems to be pretty well spec'd.
Like the other 'newbie' we plan to also convert it into a Cafe Racer.

A few areas of  immediate advice:
1) I need to change the tank, current tank is a Seeley Alloy Phil Read Replica (100% perfect condition) I just think it's too big for the bike. What are the Honda model options range for a direct fit?
2) The bike also has fully restored Lester Mags (100% perfect condition) but think some traditional spoked wheels will look best - any advice re the hubs. Bike has discs front and back on an old stock Dresda Rear Swing Arm
3) Going to need to source a new rear seat (brown leather) and aluminum cowel (Cafe racer style) any one had any good experiences/recommendations?
4) Clip on's - any do's and dont's?

Thats the immediate questions, I'm sure more will surface as we progress.
Looking forward to chatting to you all and maybe meeting up if a local CB750 ride out is something you do?
Best
