Centre stand for a 1976 kz 750 b twin

Hi.  I need a centre stand for a 1976 kz750B twin, will a centre stand for a 1982 kz 750E, I know one is a twin and the other a four,but that's  all I can find in  Ireland. Thanks in advance  if anyone can help. 

According to CMNSL the part number is unique to 750 twin 76-79 B1,B2,B3,B4

Partzilla indicates the same but does list 2 different part nums. 
34019-016 not available

The Kawasaki site shows the same 2 part numbers with the second one (039) showing it began on frame num 000760 and continued through the entire run of the 750 twins, at least that is how I read it.
I do not have one to measure for you, but would/hope another member here can do so for you. I do not know but maybe if you learned what the stock one is (size height width etc you might be able to find another one that meets those needs.
