Point taken, but in reality you may as well build a replica from a good HQ van as use what used to be a Sandman. If the one you find with a good body happens to have once been a Sandman but now has lost its chassis then build a replica from it. However you'll pay much more for this than you will for a normal body (like 4 x as much), and in the end the final value won't be much different.
