Nah, single carb. Wasn't it the 1300GT that had twin SU's?
Sadly, I was 16 & 17 years old when I had it. In my youthful exuberance, the difference between what I knew about cars, and what I thought I knew about cars was a gaping chasm, but it was a good learning curve. I learned things like you can get a floor pan through an MOT by pop riveting a plate from a galvanised water tank onto it, then using P.38 crafted to look like welding under underseal. I also put some heavy duty driving lights on (can't remember what they were - possibly KC Daylighters) and learned the value of relays, instead of melting multi-column switches. I filled the dash-pot with Red-ex because someone told me it was a good idea, and like an idiot I believed them, which is why it needed weekly topping up. I broke the rear subframe 'jumping' over the railway bridge at Doleham Halt, just outside of Westfield 🙄 It was used and abused. Felt like I had it years, but in reality I had a Mk3 Cortina by the time I was 18, so didn't have it much more than a year.
