I'm having some trouble on replacement body mounts for my '78 pickup. I tried getting the correct mounts special ordered through SOR but, after much searching, they were unable to find them anywhere and Toyota Japan says that they have been discontinued. The mounts for the earlier (US market) 45's, however, are still available. What is the difference between the two? I looked at a friend's late 1960's LPB and the mounts look darn near identical. For that matter, they look pretty much like the C-clip style 40 series mounts. Until I get this sorted out I just order some 40 series mounts to see if they fit the bill. They haven't arrived yet so I thought I'd see if anyone else has run into this. The parts fiche has two different part numbers for the 40 and 45 mounts but I figure that if they fit my frame and are of a consitent thickness at all 10 bed mounts, I should be okay. I suppose my main question is this: Has anyone used 40 series body mounts on a 45 bed and had it work?
