is their anything that i should keep an eye out for on the chassis

Is the chassis you're looking at a F15A or another FGT? Main thing is to make sure the chassis is intact front to the rear, and then check for rust, not usually a big problem with these... also look to see whether it looks true and straight, and also look for other signs of butchery.

Just so you guys know, the 48 and earlier motors circulated the water different to the 49 and newer motors so when you change the heads you have to do some fiddling with the holes in the block to prevent heating problems. I forget which holes are involved. If you find a 255 Merc engine the crank and rods and pistons will fit in the 48 style engine. I suppose you don't get those Merc engines down under though. Theres always ebay.

It should be a F15A but wont know till late this week or next when the rain stops so i can get into the yard to have a look, but should be a F15A

dont forget that if you want to use the 21A disy you wll have to change the camshaft . the waterpumps ase different. there are 3 different pumps for the 8BA . you will need 2 8RT pumps.

I am going to take Tony's advice and leave the engine that is fitted because it runs so their is no real need to change it at the moment
but thanks for the info John
