Go for it.
From the pictures it look like it's got the original drive live. The listing also states 'kevlar' band these are much stronger than the original cotton band linings which you can soon wear out by slipping the pedals, that said kevlar can generate a lot of heat on the drums which are prone to cracking.
The handbrake can hold the clutch pedal in neutral - the middle , press the pedal all of the way down for low, release the handbrake, let the pedal all the way up and you're in top. The middle pedal is reverse, the right pedal is the trans brake - you can use any pedal to slow down. Right steering column lever is the throttle, left is the timing advance and retard, also looks like it's running the original trembler coils albeit new plastic ones.
T speedsters are great fun!
