Listed here are a set of 12 machined aluminum stacks designed to replace those for the 1/12 Revell Ferrari GTO.

These stacks are slightly smaller than the kit pieces for more accuracy. Dimensions are: .200" (5.08mm) height without mounting stem, .170" (4.31mm) major upper lip diameter, .129" (3.27mm) lower body and a .097" (2.46mm) bore close to bottom.

Upper lip is contoured inside and out and all stacks have a milled flat to siamese close together. Finish is extremely fine. Pic was taken close to ruler in case you have other ideas for other usages.
