classic RT sear question

[sdn137]

I am trying to ressurect a classic RT that has been sitting unused for about 12 years. Thought I lost it in a move, but found it this winter. The sear is chipped on the bolt catch, see picture if I can get them to upload. I believe it is a carbide tip. I am looking to replace the sear and came across one for a RT Pro. I have read mixed answers on here, just wondering if this will work for the classic. Some have said no, some have said just adjust the rod. None of the sears I find have the carbide tip, so I'm assuming AGD has moved away from them. ( been out of the game for a while...)
Thanks in advance for any help!
