i have two questions, and i'm wondering if anyone here can help me out:

i drive a 91 mazda b2600i xcab (cab plus?), and as i hear is a popular event for these trucks, one of the clutch cylinders needs to be replaced. is there a way to determine whether this needs to be the master or the slave?

secondly, i'm thinking of upgrading my shift **** to something a little more exciting. are there any limitations as to what kinds of shift ***** are compatible, or will any shift **** i find on ebay do?
