would the new body fit a gen one RB5 ??

Well Paul. I think you will have to admit, it was well worth the wait.
I have to congratulate you on your attention to detail, the car looks stunning.
Pat on the back to your painter as well. He has done a good job. I understand what you say about the shell, I think the beauty is that it is instantly recognisable as a Vega.
Keep us posted how it performs. Enjoy.

Yes gen3 shell will fit a gen rb5, I ran one like that indoors last winter
