I did it on my '53 and love it. I also got the coil from them too. The square grommet that comes on the wires is a PITA. I cut it off and used a small round one. You can't use the stock dust cap either.
I was thinking about installing a pertronics electronic ignition in my distributor and doing away with the points and condenser style ignition. I have used them in old chevy trucks and they seemed to work well I was wondering if anyone here has gone that route its a pretty easy conversion.
