Hi Richard!
Very credible concept, very well executed, bravo! Packaging is king with such projects, and yours is top!
I used this same Jag rear-axle and "cage" in a 68 Charger rear-engined concept, and it was fun. My memories tell me, however, that it had a fairly wide track. The Charger was able to swallow it as is, but, did-you have to narrow it?
Just curious...
