250R a-arms on 300ex what bushings??

[enduro400rider]

i rebuilt my whole quad over the winter and went with a 250r front end set up on my 300ex. its been months since i put the front end together and i cant remember if i used 300ex or 250r bushings. now my problem is the bushings seem to be junk, i want to replace them with a Urethane set. my front end is wobblie i can see slight movement in the a-arms were the connect to the frame so i am assuming its the bushings. what bushings do i need to order? 250r? or 300ex? thanks

You'll need 300ex bushings. 250r ones are too wide for the 300ex frame mounts.
