 Generally speaking, you can adapt any Lucas 23/25/45 series distributor to the 907. 

Early on, I ran a Mallory distributor designed for an MGB, that ran just fine.  I did get Mallory to add an oil seal as it had a minor oil leak.  I currently run a Lucas 45D vacuum magnetic from an Esprit that wires right up to my MSD - very smooth.

Don't be scared by the advance curve.  Hundreds of weight and spring combinations are out there so you can get exactly where you need to be for low RPM driving.  Besides, once you put in new pistons, cams, carbs, the original advance curve has to be modified, and the only way to optimize it is to use a dynomometer - $$$$.

My suggestion:  Go with a rebuilt unit from JHPS; or if you want to go cheap, find a 'new' MGB distributor that has the features you want, and just swap the weights & springs  from your 'old' JH distributor.
