Ken...I no longer own the '73 I built around 1995...I think it's been thru several owners and modifications ....and I believe it is now on the west coast, but I've never conversed w/ the latest owner.
I think Marks HemiDuster was built around '98 or '99 and Jim's HemiDemon was just completed late last year...and I'm currently working on a front end similiar to the Demon for a '67 Cuda.
HemiMarks HemiDuster has been featured in several mags...and I'm sure Jims HemiDemon will be also as soon as it's seen outside this site and his hometown.
you did nail it...all were designed to look like a "factory" install including under the stock....no scoop... hoods
