I would probably have to get the stronglight 49d crank extractor to get my current 93 SL crank off just to get at the BB...
Hello and welcome to the forums!!!

You sort of answered my biggest question as to whether this bottom bracket (BB) is compatible with your cranks and frame.
I agree with some of the others actually buying this before you know the problem isn't advisable, unless it's dirt cheap.
Your first order of business should be getting your cranks off and inspecting your existing BB, as pointed out the issue could be something other than the BB itself.
Where are you located? If you update your information to include a location someone may be near enough to offer to help you out.
OH I should have read more you already bought the BB
You really should get the correct Fixed Cup wrench for that BB
I'm not sure if this is it or not.
A Stein Fixed Cup tool is a great item to have to hold the wrench in place. There's ways make an OK one, which I've used one, but nothing beats the real thing.
Good specialty bike tools can be expensive, again if we know where you are someone might offer to help. A pint or two, as well as new friend, might be a better investment than a few bike tools you may never use again.
