Mark ... I read your comments over and over to see if I or we could help you find this car a new home.I will start off by saying I have been building vintage Mustangs for the last 45 years. So this is thru and old mans set of eyes. Some of my earliest cars to some of the latest builds including a couple of conversions like yours. A wise old man told me 40 plus years ago when you are done with who will your car appeal to.? I thought everything I did was an upgrade and maybe it was but others didnt like my upgrades. So when it came time for a new home I listened intently what others thought. Most people want an original type car with LIGHT custom touches that can be changed out if desired. So on a similar engine swap as yours I found people hated I know thats a strong word my modern drivetrain install. I chose HO 5.0 5 speed set ups. The engine compartment looks like Frankensteins wife with all that going on. So I removed everything that looked like it was modern and put a 4v carb and aluminum intake with all vintage components and accessories. It was much better recieved everywhere I took them. They also sold much faster. A quick run down to the car wash with a vacuum, remove all dirt and debris inside and out will make it more presentable. Tidy up everything like trunk area, wiring, install a spare tire on wheel, it wouldnt roll too good without one. Devils in the details. Best of luck on the sale.
