PA Gear Ratios

[GRaw505@aol.com]

Has anyone come across a modification of the PA gear box.  A couple of years 
ago when Pip Bucknell visited while researching Bobby Baird's R-Type he 
mentioned a reasonably common mod in Australia.  This involved some slight 
machining to the gearbox end plate to enable Ford Mexico ratios to be dropped 
in.  Any help would be appreciated.
