Need Allison V1710 or Merlin(Packard or Rolls Royce) V1650

[Spitfire1942]

In process of building MJ-100 Full size Spitifire. Building mine as MkVC with Eagle Squadron paint. I'm looking for Allison or Rolls Royce V12 engines, for Allison prefer Left hand rotating, would prefer Merlin engine since intake is on bottom. Also for Allison, will take earlier versions as long gear box is available with engine, no extension shafts with remote gear boxes, too hard to find them now.
