292's bolt into anything that a small block will fit into, you should be able to use any of the small or big block conversion brackets. I really doubt anybody makes a bolt in kit, so you are just going to have make due.
Front mount will work as long as you you use side mounts on the transmission. You must three points of contact or it will just twist and lay over.
Cut the front crossmember to clear, then add a new one back under the motor to support the engine like its suppose to be. 2"x3" tubing is not that expensive and makes nice looking cross members.
