my spare part manual shows 5 bolts for LD20 and 6 for LD28 balancer.
im guessing but if you swapped the pulley and flange as an assembly it should line up.the V/belts have the same spacings.
on my LD20 the a/c belt is a 13 mm on some 6 cyl nissan it is 15/17 mm belt.

T/stat housing top should be the same as any L engine,and the lower part is the same as LD28.

LD20II only shares the t?stat outlet.the rest is model specific so you need to know where it came from.

in van aplicationLD20/LD20II has a bleeder outlet up to a filler cap/surge tank from both inlet/outlet.

Elbow, Carimbo discovered an '81 Diesel Sedan in a JY. Today, I had two hours with it and pulled the t-stat housing for you. PM me your address and I'll mail it. It cost me about $6. Someone had already lost the bolts though, so you'll have to buy them separately.
