Hi Josh,
Firstly, its nice to hear that your build is still making progress, keep at it
As for being a "shorty" ( everyones a shorty stood next to Tatey

),
I,m 5ft 8 in tall & the standard roll bar as supplied by Ash G seems the perfect height for me, & i,m having my seats set a little higher than other builders, basically I like to be able to see the top of the front cycle wings from the drivers seat, and I,ll be wearing a helmet when driving & the roll bar still has enough height to offer me protection.
As for headlights, ( as Tatey has said ) I got mine from Kitpartsdirect for £35 plus £7 delivery, they are at the cheaper end of the scale but will pass IVA & do look good on the car, the only downside is the side lights in them are not wired in , so a little work wiring them in is required.
Have a look at the photos on my "Big Day " thread in the Chassis section, the photos in the most recent postings show the headlights & the roll bar fitted.
I,ve used the sierra master cylinder, tho some are 22mm dia & some are 40mm dia for the hole required in the pedal box plate so its best to wait till you have the M/C before drilling the hole.
As for pedal rubbers, most folk seem to glue "Grip Tape" available from "Car builder Solutions", .
hope this info helps .
cheers
andy
