hi, thanks for the reply, everthing you have said is spot on but i think the coller is 7/8 inch as aposed to 3/4?????, the two holes in the front plate of the carrier were the block bolts to are a different size on my carrier, looking from the front the left one will take a 3/8 bolt but the right one appears to small, was
this tapped out to take a 3/8 counter sunk set screw with a locking bolt on the inside of the carrier????
