take one out and measure the cylinder, extended shaft, and total length. I give you a couple of places to look at. please don't get me wrong, but it looks like you are a bit none mechanically capable do some stuff. Kit cars are not factory turn-key, always something to fix, redo, etc that are made from 100 different manufacturers' parts. on top of it, money-draining hobby. good luck let us know what did come up with.
