Looking great
May I ask.....the extra braces you have put in beside the engine bay, are they welded to D1 & D2 or do they just pass eachother? ( can,t quite see from the pics ) , it looks good
I,d suggest 2mm steel floor , or even 1.6 if you are mounting the seat runners on boxed tube welded into the chassis between the tranny tunnel & cockpit side rails.
Nice work
cheers
