FLH Project Consideration
Depending on where and how big the crack is the tranny case can be welded. If the crack is across the seal face it may be better to get a new case. I see this as being your biggest money pit for now. You need the tranny so this should probably be your first priority.
The sky (and bank book) is the limit for you. Build what suits you. There is so much you can do with this. Set the frame up somewhere you can start hanging and mocking things up.
Start with the stock parts you have. See what works for you, what looks good. Make an inventory of serviceable keep parts/not serviceable not keep parts. Then divide the not serviceable parts into two piles of garbage and trade/sellable.
Make a list of the bike swap meets and start haunting the bike shows you can get to find/trade parts. (you might want to shop that cracked tranny around and find someone who needs one)
An old shovel is never really done. You will find yourself wanting to add/subract things over the years. They are the Lego Blocks of Harley.
I would caution you not to modify any stock parts such as the frame, forks and motor. Hot rodding the motor is one thing, but throwing out cylinders, cases, etc is something else. (unless you have to)
Your bike looks awesome!!!! I would definitely keep the old brakes. Just my personal preference as I love the look. The forks look like late model Showa, but i"m not sure. They look good. Old style swingarm, definitely cool.
Enjoy this bike, it will give you decades of pleasure as mine as given me. Of all my bikes, my nearly 50 year old shovel is my favorite. Just walking over to start her up knowing I"m going for a ride puts a smile on my face.
PS, those are two piece bars on my bike to give you an idea of the look.
I have the swingarm on but am not sure of the orientation of the axle. Does it insert from the right, or the left?
Oh, I have a pretty nice speedo... And an S&S Super E too!
A lot of cleaning coming up...

Id expect the lower left rear forging number to be 47654-73 and the lower R-H rear forging number to be 47652-73.
I imagine the gusset plate in front of the left rear downtube is original to the frame. It was fitted as original as of about mid-68 models but it was available as repair part #47261-68 for frames back thru 1958 models.
Blocks at the back of the rear downtubes are not original. H-D attached rectangular two-hole blocks in that area as of 1977 models and they were a bit lower than those.

Swingarm is 1963 or later. Ill guess somewhere from 63 to about early-67 judging by the position of what may be a hose clamp screw? Forging ID may be on both axle clips. For more info about round swingarms heres a link to a thread I started on the Panhead and Flathead forum in 2016.

Regarding the one-piece handlebars you already bought, you could cut them in half to suit the handlebar clamp that came with the bike. Ive done it with several bars over the years.

I am collecting a few parts atm, and will be cleaning & scouring what I have. Slow going for a while...
I will keep pics coming to show what I have and for identification.
This bike started life as an FX. So it came with the mid controls. Actually the pic is a bit old now as I put on the longer controls for footboards.
I ordered this bike new in 1975 and took delivery in Germany in 1977!!! Paid for it with my re enlistment bonus.
It has been through many many many different incarnations over the decades.
