Ahhhh.......I was thinking the problem was elsewhere.  Good to know man!

Got it ready yet?  We want pictures!

Yes I know, getting my Cooper STT's put on today    Maybe I'll find time tonight. 

Talked to Quaddog?  If I remember correctly he had a similar problem.  I think he did something with the threads to make his fit.

Sorry I missed this... yes, one was fine, the other had to be reamed to size.. it wasn't the threads, it was the non-threaded section.. it was machined out of tolerance, although I could never get  BDS to admit it.. it's not like they MAKE them anyway.. they just order them from a jobber..

So then you drilled out the hole inside the extension? ... I need more toys 

Yeah, basically, I didn't use a drill bit, at first I used a piece of emery paper wrapped around a drill bit, but when I realized I needed a bit more metal removed, I used a stone in a die grinder and just carefully clearanced it a bit.. then finished up with emery..

Shouldn't have had to do it, but it was faster than waiting for a replacement extension that may or may not have been any  better..

It was the extensions that varied, one would fit right on both struts, and the other extention, the other wouldn't fit anything.
