After about 60 years of wanting to get an Avanti I am in discussions to purchase a 1964 R2. At the moment this car undergoing a full body-off restoration. It is currently configured with an automatic transmission, but the restorer has all the either rebuilt or NOS parts to convert it to 4-speed. My question surrounds the "feel". Does the 4-speed shift easily or does it require some effort? I've owned many manual transmission vehicles but I will be turning 70 this year and if the shifting requires effort I may just leave it configured as an automatic. With the car fully apart at the moment it would be easier to do the conversion. I look forward to hearing your comments.
