I use a type 27 battery in my positive ground TR2 and TR3.   The 
posts are on the firewall side with this arrangement.  I also use the 
the type 27 in the TR4A which being negative ground puts the 
terminals on the engine side.  So it does work either way.

If you prefer to have the terminals on the other side, a type 27F can 
be used which has the terminals reversed.

As far as cable length, you MAY have a problem as the REACH is 
further to the engine side.  I recently replaced the 27F in my TR4A 
with a 27 and had to get a new ground cable as the original would no 
longer reach.

Hope this helps.

Cheers,

Brian
