Uh, aren't the kits one size? U need an SBN rebuild kit.

And to find out what size it is measure the bottom.

Its a sbn 44 or 46, the rebuild kit works for all of them unless you are doing the throttle shaft rebuild, in that case you will need to know the size of your throttle plate

thank you to all who helped , i believe it a sbn 44 , so a sbn kit will work, you are all awesome and thanks again.
