Can anyone tell me what it should cost to buy a thermal fan and have it fitted to my 1979 VB Commodore? Thanks.
60 - $ 200
Depends where u look and what you are after for your setup
Look at places such as
Wreckers
Ebay
Autoshops.
If you want an answer today, you could try twin VT fans off ebay for around $150 +
ps. Make sure when you buy your thermo it comes with the wiring and thermostat etc.
