78 kawaski kz 750 need info on stretching

What's up les I heard u were the man to talk to so I ended up buying a 81 kawasaki 750 kz an would like to stretch it an would like for you bud to make me a swingarm how much would it cost me also I would like to do a wider tire on the rear could I do a 180 rear tire without any modification

I have a 4"-6" arm here that can be setup for the 750. Arm is 4130 chrome moly. The only difference at this point is the head tube is narrower for the 750, easy setup in mill to change. It's set up for disc brakes and It comes with brake arm with heim joints installed. Set up for 25mm axle and comes with 4130 hollow axle to fit. I'd have to look where the shocks mounts are located but I do know they are relocated to lower bike. Also comes with a complete new bearing kit. $395 shipped
I'm leaving this afternoon and won't be home till May 6th
One of the two arms on the left is it.
