QLT By MARSHALLTOWN BF9 Rock-It 2.0 Bull Float Bracket

hi I have a 48" square bolt float and have no info on how made it , the hole pattern seems to be 2 3/8" x 3 1/8" BF9 bull float bracket fit it?

Can you adjust the tilt or angle range, I know you twist to go up and down... just curious if there are any addition adjustments to fine tune range

What type and size bolts are use to mount it to a Fresno?

Is the bracket metal or plastic?
