What's your record time

Two hours to R&R a trans in the daily driver '78 Fury. On frozen grass, in a quick built lean to made of scrap lumber and black plastic, no heat at all, -20°F.
We worked in shifts. One under getting **** loose while the other two were in the house keeping warm.
Work until cold, slide out, go in to get warm, the next would slide under, repeat, rinse.
Wow, you had some dedicated friends there, not to mention yourself.
