What is the plastic that holds the seat belt as it comes through the seat called. I'm trying to replace the ones in my 75 Malibu but can't seem to find any anywhere. Maybe the correct name would help. Thanks in advance. Dave

It's a guide.
You'll find them NOS on eBay Motors.

I knew the part by your shoulder was a guide, is the part where it passes through the seat cushion also called a "guide" ? It's the part that holds the belt up off the seat cushion.

That's probably a guide also. Maybe an escutchen.
Find an old GM parts book and that will tell you.
