What size is the square head on the toe cam plate? I thought it was 9 mm but it feels like it is gonna round the head. Also how easily is it to rotate? Seems like its gonna take a good amount of force, tried it loaded, and jacked up and its still not roatating.

 

You use the bolt head on the other side.The bolt face and Plate and threaded part are ONE..then the nut slips over that square end.
That square part is just the end of the threaded rod.

 

Thanks, he service manual and Haynes showed a wrench on a square head. One more thing tho, I am looking at the correct bolt, right? The outer bolt on the trailing arm that ties it to the sub frame.

 

that is where the bolt is,although I do not think it is for TOE.
camber or caster,not sure which..sorry.
( I get an alignment shop to mess with stuff like that.)

 

Caster doesn't exist in the rear, and camber isn't adjustable in a stock car. The adjustment if for toe.

 

As I said I get the shop to do stuff along those lines,so I could be wrong,and If so,then I apologize.
