Guys one of my cylinders has a leak at the fitting because I had to drill out the old one and retap it.

What are the real differences in early to later because the replacements are well over $100 where later units are much less.

They look exactly the same.

The short hardline connection on the cylinder is in a different location.  You have to bend that to get it to work.  It's not too hard, I did mine. 

I finally found a picture, not so good but you'll get the idea.  Also I found it was easier for to swap those short hardlines from one side to the other, not as drastic of a bend and less bending.
