haha nice one with the bracket
my hand brake is further back and yes I shortened the cable . like said above try and lower it if possible mine lands nicely inside my arm when reaching for the gear lever, also I padded out the tunnel top so the handbrake appears lower.
Seats , I used westfield sports seats
if you troll through my build you will see photos of seat and handbrake if you need more shout and I'll take some better ones
