I installed them on my 49 Sub after trying to rebuild my originals. Bought some repros and they were just as bad. The Altmans work good but there is a lot of cutting you have to do to the door jamb and the operating link from the handle to the latch needs to be bent and hammered to get it to work properly. It is a lot of work but in my case there was no alternative. Also be advised that with the Altmans there is no way to lock the doors with them installed.
