Hi Ryan,
the importand thing now to do as you know already that the cylinders are the same is to match the correct pistons with the cylinders you have... Messure the cylinders and the pistons and match them correct... If you don't have the tools to do it go to a workshop and ask them to messure them for you... I guess they will do it for free and you will be sure that you have done a nice and clean job...
Cheers
Michael
