I have a 55 i was working on and both sides of the body bow out so far from the side of the chassis glueing it to the chassis wont even work!, it's now back in the box 95% done never to see the light of day again.
All Australian are my choices,
Ford XW/XY Falcon GTHO
Ford/Holden V8 Touring cars
XC Ford Falcon Cobra, Road or race car
Google them, all good choices i reckon!
