Well, those posted instruction sheet pics by Keyser of the Get Smart 4-cylinder kit help explain a little bit of my confusion regarding how to install the V-8 engine in the reissued Tiger kit. Part #37, (the V-8's Engine Mount piece), doesn't even exist on the Get Smart instruction sheet. (It looks like that 4-cylinder motor is held in place by the transmission cross-member in the rear and the lone, upper radiator hose upfront). So now I'm guessing that Part #37 is an add-on piece for the V-8 to mount to, and the "vagueness" is somewhat explained! I'll post more info here once I do some dry-fitting and make a determination on how Part #37 should be glued in-place.
