Thanks for all the advice will give sk a call.
Also, I have one of the square metal lenswrench stamped spanners, however the lens in question had one of those small set screws to prevent it from spinning in the lens board. When I received it thelens had some wobble on the board so I took it off. Found 2 grooves in the hole on the board that looked like one of them would hold the screw so realigned the front element with that and started cranking on the ring when after a turn it wouldn't go any further. Stupidly thought I was pulling the lens into it's proper place when in fact I was just pulling the threads out. Let that be a lesson to you that you probably already knew: don't force anything camera related when it won't move.
