Hi guys I
I have picked up a 1990 kdx 200 that I am putting the engine in a 2000 125 , I believe the swing arm has been modded or is off something else and also the shock , can anyone assist with ID of these please

Don't know about the shock, looks like an E-sries one but can't say for sure. The swingarm looks like an E-series one that someone welded a sharkfin on
