So the bracket is bolted to the block. The insulator bolt into the mount has is a bear for me. Oil pump, power steering box, headers, and the mount itself are conspiring to prevent me from torquing it down. I can't get a rachet in. A std box-end wrench, squeezed flatter in a vise still is too big an angle to turn. Open end wrench is out of the question. Anyany have a simple idea? 71 E-body, Debeveck k-frame, "stock" mount. Pic is rotated 90deg left. Nut is on rh side of pic.

That is one of the fasteners that need to be installed and torque before installing the motor

I've done HEMI mount replacement in the car E/B body, even with headers, chances are you'll need to unbolt the headers off the engine for some wiggle room, grind down a 12 point box wrench end really flat, bend it to whats needed to get it in there....cake walk

You need more tools. That's why God created Harbor Freight.

and those are perfect to heat, bend, cut, and weld on, to make what you need for the job that will be used only once.
i have many of those kind of tools, plus a 5 gallon bucket of broken tools i dig into often to fab up more !

The oil pump is easy to take off then you can tighten the mount and then reinstall the pump.

I use a 3/4 inch flare nut wrench. Open end gets you past the protruding insulator stud.

Uhhh, nah. Not dropping the k-frame to install it. Not pulling the engine to install it, then fighting to get the bracket on the engine. Its the nut on the RIGHT. Pic is rotated.

Flare nut wrench is 6pt, thus 60deg angle to gain any tightening. I don't have 60deg swing there. Not sure if I can get 30deg. I think I'll further flatten a12pt box wrench, and if it doesn't fit, I'll relook at pulling the oilpump. If either works, I'll post a new photo. A big thanks for the suggestions. Maybe it'll run this weekend.

If you pull the oil pump make sure and remember to put the long bolt in the pump before you install it. It's the last one I take out after removing the other three. It's too long to remove and stays in the pump as you remove it. It drops down and will hit the k member but is out far enough to allow pump to be removed or installed easily.

cheap 12 point wrench. grind it thinner to fit maybe ?
