z1 exhaust on 1000 ltd

Seeing as the decision has been made for me that i wont be doing the z1 restore, after i once again get all the parts re-aquired that i had (wheels gauges seat etc) will a 4 jnto 4 mount up correctly to say an 80 1000ltd frame (if i can find one)?

I have seen Z1 4/4 exhausts on 1977/1978 A model KZ1000's and on the 1979 Germany-only KZ1000-S model (which was a reconfigured KZ1000 D1/D2 model). I have not ever seen a set of Z1 pipes on a bike with a 16 inch rear wheel...not sure if there are fitment issues.

Yeah, I'm not pulling the trigger on $1200 exhaust for a not sure if it will fit, maybe Cloning a Z1 isn't happening. Love to smack that punk who stole that 73 and parts from me with a hammer. Oh well, back to the drawing board
