Hi thank you.The 1955 one came to the Netherlands as a chassis and cab then the rear end was fitted.The 1957 came from Sweden i got that one 3 weeks ago.They both have petrol 223 engines.I have took the large water tank out the back of the 57 i plan to drop the body i think with the tank,the tow bar and front water pump i have removed about a ton in weight.The 57 has done 15,000 miles and the 55 has done 12,000 miles.I have took out all the floor as well out of the 57 and i will put in 5mm aluminium plate for the floor.And the 57 i think i will use all the time.The trouble with having trucks from the USA if i need parts the companys who sell the parts to me charge loads to ship them so a part for $18 they will charge $35 to post it.Thats the trouble being in the uk.
