GTs w/V8s

[wzehring@cmb.biosci.wayne.edu (Will Zehring)]

Fellow fiends:

I'm gathering from the current discussion on the Rover V8 that the later GTs 
had some sort of change in the firewall and/or tranny tunnel that makes 
fitting a V8 easier.  yes/no?  If "yes" when is the earliest model year GT 
that this change(s) were made?  Another neophyte question:  what sort of 
tranny does one use in such a conversion?  Can one keep the original rear 
end or should such a converted car get a "stronger" diff?

thank,

Will Zehring
