It's been a long time since I installed these bolts.
I checked my builder's log and the lower firewall was done in March, 2002.
The bottom was glassed in December, 2002.
Not so much due to the time, but, due to the layups done after these
bolts were installed (should have covered the shanks with heat shrink
tubing) they had epoxy in the threads and there was no way I was getting
nuts on them let alone brackets.
To solve the problem, I used an adjustable die. I set it quite
loose so as to not cut new thread or damage the plating. Worked great.
The epoxy really doesn't stick well to unprepared metal, and, the die caused
it to crack & break and fall out of the threads. |

Brackets, however, are from the Cozy Girrls. Note
there are no cotter pin holes drilled yet. I suspect they don't add
these to allow the brackets to be used interchangeably left to right. Also
note the extra washers. I do this to prevent the locking nuts from
engaging fully. Yes, I'll remove the washers upon full install and use
new nuts as needed. |
