Charles. First off, you have a VERY rare car. I too have a 1959 OTS automatic of which they only made 72. Over the past 1o years we've only been able to locate 6 surviving. Please send me you name, address, vin, etc. and I'll add you to our list. Yes the car did have a servo and some (not mine) also had vacuum reservoirs. All are located in the left wing above and in front of the battery. Panels can be removed to gain access. I am told that the E-Type servos will work in this car and the originals are all but impossiible to find.. Pictures of my car are on www.patsjjags.com which may help.
