Driveshaft Alignment Tool

[McCohens at aol.com]

Anyone make one for alignment with the exhaust system mounted?  After playing 
around with my 200 20V driveshaft it seems something could be made to clamp 
the shafts and hang below the pipes.  Not to hold it straight, just to show 
when the center bearing alignment is correct.

After a couple of trys eyeballing the shaft I got mine pretty close, but 
there is still a little noise when accelerating hard in 1st and 2nd.
