My 82 F-150 is half and half, I hate it.
Since I haven't worked on an SAE car for awhile, I guess Metric, BUT I like dividing by 12, not 10. More possibilities (1,2,3,4,6,12 versus 1,2,5,10). And who thought that 5.5mm was a good size for a bolt head? I still can do the math for fractional SAE sizes quicker than trying 7,8,9 and finally 10mm.
7mm for half the bolts holding the dash in, 8mm for the rest. SAE it wold have been... 3/8 for all, MAYBE 5/16 for some, but probably not.
