Clutch problems

Are there two options, one with PRT & one without, will the device that has more clearance fit the one requiring less?
If so why not make one that fits both?

I think you could easily make this yourself as long as you can weld, but it would be trial and error to get the dimensions right. For me it was easier to buy the kit. I was very pleased with the result. Before the mod I could hardly change gear.
