Jahns piston

["COSTICH,ALAN (Non-HP-USA,ex1)" <alan_costich2@non.hp.com>]

I'm building a 1840 MGB motor for vintage. I had hoped to use Jahns flat
topped pistons that are forty over. 

Saddly, the machine shop I'm working with just informed me that of the five
pistons I gave them, two have a compression height better than .0625 too
short.

So, I'm in need of one piston. Anybody got one extra they might wish to
sell? Or, perhaps a set of four at bargain price? 

Thanks.
