MyHeadisFlat welcome on board. This forum is GREAT, not only for the informational part, but the spirit. As you can see from the posts above, open minded people can have different opinions without a fight. That does NOT happen in so many many many other forums I'm part of.
This forum has so positive "atmosphere" whether you talk original, customized or inserting modern tech into old Moparium. That's the way I like it, and I like it here.
Now I stop slapping my hands against your back and back to your car;) I like your RPU, reminds me of my '27 tracknose roadster I built from scratch earlier.
I agree with others that chopping your ragtop doesn't do any good to the looks, and I still like customs. Carson top or similar are ugly to my eyes in so many cases. I was concidering even to chop my businesscoupe, the more I look it and the pictures of chopped ones, the more I lean towards keeping it original what comes to the height of roof.

And this my '62 Lancer STW with flaked roof, blue flake tuck'n'roll interior
For the Hemi, go for it, thumbs up if you feel like converting it. To me any engine in these cars is cool as long as they are driven. Well maybe not Nissan diesels:D
