Be wary of any used safety bell housing (a.k.a. scatter shield) made by anybody in any design that has already contained a failure. You can tell if high speed heavy sharp objects have been bashing around inside. Example: The cast steel Cobra model for five bolt engines will often be distorted in one to several directions after a big component failure inside of them. Just because bits and pieces don't come flying out in an event doesn’t mean the unit didn’t get stretched one way or several.

I have personally not had any issues with original COBRA five bolt housings that have never had to contain a clutch/pressure plate/flywheel/transmission input failure. They have fit and aligned great with no need to shimming or adjusting position in any way. On the other hand, I have gotten ones that got “well used” after something inside failed and started a chain of failures and it was sort of stretched to one side a little to over an eighth inch. Example: In 2015 I had my local automotive street and race engine shop measure one with very obvious scars on its inside and it was quite distorted and in the end not usable; wall art.
