I have a 93 accord distributor (TD52U) which has oil leakage problem. The cap and rotor are fine. I just need to replace the housing.
My friend has a reman 91 distributor (TD31U). I don't know if they are interchangeable. As I know, 93 is exterior coil while 91 is interior. Can I modify the 91 housing to fit my 93 cap and rotor?

Any suggestion will be helpful, thank you.
