Thank you for the compliments! I have some cosmic arches I'm going to offer up and tape on, then take pics but i think i will remain archless as it will pain me to drill the 1977 shell!
I think ill end up going Minilite / GBs with no arches as a happy half-way!
@Bike1769 - The reverse's are 4.5 with 165 tyres for a bit of bulge - and yes spaced out for the poke. They sit basically flush on normal, no spacers drums all round.
