I tried finding it yesterday but gave up..
Sounds like it's one of the Yenko cast alum. blocks like Barnhardts car has and not the one w/ the Yenko crest/logo..
Is it correct that the Y-E-N-K-O lettered one is the earlier one and the logo style the later...always trying to clarify this and if it's been noted here previously, I either missed it or it didn't stick?
