Title: Head Bolts
Post by: hywayman on 26.07. 2019 08:20
g'day all, can anyone help me with part numbers for head bolts?
as i've discovered, the '46-'50 engine has 7 bolts & 2 nuts whereas the later must have 9 bolts?
looks like 6 bolts are around 2-3/8" long & the centre around 2-1/8" long
thanks in advance
