Thanks Matt, actually I just finished unwrapping all the tape and the wires are in pretty darned good shape. So far there is approx 5-6 wires to replace(red n blk ammeter wires are way stiff). Most ends look good. Welded splice is even in great shape.
I did the googling without much luck for fuseblock.
I can get new dimmer switch connector SMP #S64 which is good. Headlight connector I think will be fine too, so a bulkhead connector and fuse block will be needed.
Thanks Matt.
