I think mine are 6” OD, 1/2” center hole, 1/4” thick flat plate steel, found somebody on eBay to water jet them out for super cheap, like 25 cents per.
I would not suggest my way for a new bushing install , but in my case I have good bushings and did not want to remove the dogbones
You don’t need the angle iron. I used 1 by wood pieces and a wood splitting wedge. Fell right apart.
I did not want to apply heat to the rubber bushing of welding pieces on. I did bolt on because what if I need to press it apart again from that direction?
