Want to replace the rear speakers on a regular cab GMT400? Time to remove half the interior and make you buy a T45 (or T47, I can’t quite tell) bit because of course. I guess I’m not having lunch anywhere other than McDonalds after all.

DISCUSSION (12)

When it comes to interiors, GM is like that kid that refuses to ask for help, but really should ask for help. I despise doing anything that involves taking apart the interior of the Blazer

It sucks, but I’ve already got it half-disassembled, so I might as well spend the $10 on torx bits.

I don't understand how 80s and 90s GM products wound up with torx fasteners

Because in the 80s and 90s, very few home mechanics had Torx fasteners, so this was a method of having to get it dealer-serviced for some things.

Wow that's shitty of them, but it makes sense

Trust me, it isn't just GM that uses torx for interior components. BMW uses them too and I think I've seen a few in the Fusion too.

Yeah, it’s just that GM uses Torx fasteners on the weirdest things and in the weirdest sizes.

Also, since they’re seatbelt anchors, I have a couple of questions.

1: Why is the bolt metal but the bracket plastic?

2: Why the hell didn’t they go all the way to a T-50?

1. I imagine that has something to do with wanting the bracket to break before something else that’s more expensive to replace, maybe?

2. The same reason for using torx at all, I assume. T50 is probably easier to find than T47. Also the same reason BMW uses 7mm bolts for some things

Alternate reason for both - they were probably high

Yup.

Fair enough.
