Nah, most old GM's of that vintage you just need a tetanus shot after working on. ;)
I have a belt driven 5 hp compressor. 1/2" Hose. At 120 PSI no 1/2" impact from Home Depot or Sears under $250CDN would take it off. We went through three of them... The local Crappy Tire took it off. I tried breaker bars + leverage, and no go there either...
I'll stick with my GM's. I have 18mm wrenches and sockets now - no regular sets seem to have them, but that's apparently the only size for the front suspension on the wife's Beretta...
Although... on the Acura, most of the bolts were 10,12,16 mm... not one of every possible size like on some other cars I've seen...
