[Nobbc] Disc Brake Help Needed

[KerryRBailly at aol.com]

Hi All,
I'm restoring a kit car that has Triumph Harold front drum brakes.
I want to convert to front disc brakes.
I have looked up the front wheel bearings for drum and disc brakes and they 
 appear to be the same for many Triumph cars.
I also understand that some TR 7 or TR 8's have five bolt rotors.
Please share your expertise with me.  I don't know what to buy, or  where.  
Please email or call me with any useful information you may  have.
Thanks!
