Hi, Bubba. I'm the Mike that denney47 referred to. Karl and I have the EME starters on DLE55's. Mine is in a TF GS P-47 and Karl's is in a TF GS P-51. Mine is pretty much stock, but Karl's starter had to be modified to fit inside the cowling of the Mustang. So far, they work just like they are supposed to. Here's a link to a video of my P-47.
