old mid 70's and 80's Wiseco piston catalogs

Hey guys...I'm looking for old Wiseco piston catalogs from the mid 70's to mid 80's because I am absolutely convinced that I remember Wiseco making a very limited run of kz750 twin big bore pistons ..hopefully someone else will remember so I don't think I'm crazy (debatable) ...the reason for the catalogs is a gentleman helping me at Wiseco said they do keep the old piston specs ...the problem is the information is not arranged by bike model and year, but by piston kit or individual piston part number, and the information cannot be accessed without a number ..so if you do have that number, that would be GREAT! ....maybe I am crazy, but I'm still convinced it was Wiseco ...but if you guys can remember who else made "big bore pistons" fir the twin (not you're standard 1mm overbore), then I'll try that route ...thanks all of you for any help ...thanks..

Oops! ...

I've looked for mine, can't find it. S**t! I have two good 1015 cast pistons for my Z1 I had to replace because Wiseco stopped making them. Maybe someone else can use them. I think I'll list them.
