Never tried this before!

Excuse me, but what else can you do with engine mounts BESIDES install an engine?
Nothing else is off on the stock k-member using spool type mounts OTHER than having to move the driver's mount ears back @ 3/4 of an inch.
What's so damned hard about that?

If you're going to mention power steering box clearance issues, those won't go away unless you use elephant ears, anyway, but most folks use manual steering boxes of some form, which clear just fine.

I also have done, or been involved in, a few Big Block A body swaps and have found that even the aftermarket swap mounts CAN, and do, sometimes SUCK to install.

I won't pay to make it "easy", when I already know a reasonably simple way to do it anyway.

Mark.

Never said you were wrong, I just prefer to buy the mounts so I do not have to reweld the mounts to the K- Frame. It saves me alot of time for other body modifications. Bruce
