I'm still searching for the following sizes, paying $150-200 each. I'm not particular on condition; please contact me if you have one or more to sell! These are measured in length (not including the hex head) and bore (the inner hole diameter on the small end).

2.5" length, 0.75" bore

3" length, 0.5" bore

3" length, 1.25" bore

3.5" length, 1" bore

4" length, 1" bore

4.5" length, 1" bore
