Starter Clearance Issues

Another challenge for me to over come! If you have read any of my posts I am working on a 66 Dart. I am trying to get a starter that will work with my 360 block, 904 trans and TTI headers. The one I have now is a NAPA mini starter for a 91 Dokota. I took it back and we compared to the other mini starters for different Dodges and the only difference is the wire terminal connector setups. My issue is that the starter is just touching the block which is holding the starter from mounting flush. Its very close, about an 1/8" gap where the top bolt for the starter would go in. I cant get a pic of this as theres no room for camera to focus but take my word for it! lol.

Has anyone else had this interference and if so what did you do? Grind some of that away? That hole has what looks to be a plug about 1/2" up inside it so it wont effect anything as far as the plug. Im assuming some type of oil galley? Now even if I grind some material away then the next issue will be how close it is to the headers. I know that early A Bodies are tight but this is very close. Yes I can always ding the header some to create some space and if thats my option I will. those pipes dont bend as I tried to do that on the frame rail side and I ended up dinging one of the tubes for clearance there.

Is there a different style of starter available?
Thanks
