Best Solid Bushings?

[68Formula]

So for the body bushings, I'm looking at a set of self-locking. I know Speed Tech has them and Global West. Are there others? What are the pros and cons? I thought DSE had them too, but can't find them on their site.

the only body bushings that self lock are the ones we make all others are inter-locking

Hard to tell from the pics, do they just sit between the frame and body, or does part come up from inside the frame? Tried to PM you with my email for some instructions to better understand it, but you are full at the moment. Thanks.

Any other input on the other interlocking brands?

I've had both the global west and dse brand solid bushings. Both were very similiar except the dse hardcoat put them a step above.
