ok folks, Here is where we at.....appears that the head bolts did manage to loosen just enough to cause the coolant leak....My regular mechanic (friend) was actually here to help get her started since the old 6 volt system really wants to be hesitant and needs the 12 volt jump push...takes 2 people ...

Well,Guys n Gals, I checked my head bolts and found each one of them just shy of 85ft lbs....on my clicker....I know i tightened each down to 85 ft lbs...Is it possible that these backed off....Before assembly i had run my tap thru each of these bolt holes and blew them out as well... probably shoul...

Pauly68, Well i certainly do need a little more information in regards to which side these clutches come from,??? If these are what is in the left side steering....they would be driving you to turn right.....in order to turn left your left brakes have to be working properly to lock that side and ena...
