I have one like Miker shows. Had it for at least 60 years. One end is 1/2" other end is 9/16". Works great.

I would think 1/4" is what you mean.I like Dons idea I do not know how many times I dropped mine never thought of shoe lace idea.If you have one of those sets of 1/8" drive sockets and reversible socket wrench, it would probably work also (without an extension). But you'd need to stand on the exhaust manifolds like I do when using my offset wrench. It don't need to be super tight. They got a lockwasher on 'em. The original bolt is 1/2" hex.
The threads might be 1/4"-20 thd/inch, but it has 1/2" hex head.I would think 1/4" is what you mean.
I was pointing out you said 1/8 (never heard of that size)and that you meant 1/4 but you may have a unique tool setThe threads might be 1/4"-20 thd/inch, but it has 1/2" hex head.
