Colin is correct in that no one makes a direct fit to the halogen equipped reflector. IMO, you will want to convert to the replacement reflector that is manufactured per the Ford blueprint that has the aluminized finish which has the correct parabolic shape. The better parts vendors carry those.
Ron, if you are ordering Model-T parts from Langs, they also sell a set of LED lights that are a copy of the Logo-Lites. Their pricing is good on those. Also as stated above, these new LED bulbs aren't sensitive to fingerprint oils like the Halogen bulbs were. Probably doesn't hurt if you want to be cautious and use a tissue when installing the LEDs, -but definitely not necessary.
