^^ Indeed. Sometimes it's necessary to have someone entirely custom-fab a part, simply because there are no other options with the quality / functional target you have in mind. And in cases where you MUST have a part fabbed, you instantly lose almost any ability to "push back" on the end result since you will essentially be the only beta-tester.

But in this case, a push-type conversion with a modified flywheel gives you a very wide gammut of proven and reliable options for a far lesser price tag. That's what I will be doing, once I get to that point...
