Been daily driving it for a while now. I have had to replace the 175/50/13’s on the rear with 175/70’s to get the gearing back up to a reasonable level. The info in the 98 GRM race prepping a fiat 850 issue regarding reversing the cooling air flow was disasterous in my case. Tons of overheating/vapor lock issues that all went away as soon as I mounted the fan on the back of the radiator.
Next up new carburator and some more supportive but still lightweight seats
