I'll admit, I only looked at one or two.
But, the bolt thing won't do much good
here.

Chris understood. There's no room, really, for a "spring compressor".
I've done McPherson struts, and, this is NOTHING like that since
any flimsy metal that fits between the spring coils is NEVER gonna
compress that spring.

If you held that spring in between your fingers, for example, you'd
NEVER get it to compress visibly. It's also VERY BOUNCY so it sproings
all over the place, as you wrestle with leverage tools (e.g.,
long screwdrivers).

There's no room to get a C-clamp on the ends either, as both ends fit
into a recessed slot.

It's not a 0.5-second job, that's for sure.
