As others have noted, there's no way to prove a 1970 is a W-30 without the build sheet. The VIN only indicates that the car is a 442. The boxed lower arms were used on all 442s (and any Cutlass with the FE2 suspension option). Lacking a build sheet (and most Lansing-built cars did not get build sheets left in them, apparently), if the car is an automatic and the trans is in place, a numbers-matching VIN derivative on an OW TH400 is the best proof. Unfortunately, repro OW tags are available now, and VIN derivatives can be restamped, particularly if there are big dollars involved. Lacking the engine, trans, inner fenders, etc, or any documentation, this is just a 442 shell and should be priced accordingly.
