Beer, lotsa beer. If you are a Yank working on an Aussie Falcon you need cases of Fosters or XXXX ("Four X") to understand why the Aussies did some unsual things to the basic Falcon design (like the bolts on the front guards/fenders).
No, to be quite honest the best "Tool" is being able to deal with the fact that the Falcons were built with state-of-art technoligy of the late 1950's. Far too many people on this board expect the 60's Falcons to comply with the consturction of new Asian-built cars.
There has been radical changes in auto construction over the last 50 years and working on the car in the same mind-set as it was built is the only way to approach the subject.
A good example of the state-of-art methods apploied on the Falcon is the placement of the fuse panel. People complain about having to stand on their heads to change fuses and never bother to notice the fuse box can be dropped below the dash after removing ONE fastener (hint: the chrome bezel of the light switch is the fastener. Of course the same people don't stop and thing about how to remove the light switch knob in order to unscrew the bezel (hint: feel around the top of the light switch and you will find the button that releases the knob and shaft)).
To be honest I am surprised that there are any old cars let alone Falcons left the way people try to work on old cars. |
