Anyone know where I can get these rubber coated metal trim pieces that snap into the window channels.

 

Welcome to the forum

LMC truck shows both inside and outside as "in stock", #7 and #8

Go to LMCtruck.com

Select door parts

Then door glass and parts

When asked put in your vehicle details, i.e. 1998 ford ranger

1993-2011 ranger for parts diagram

 

My truck only has. 1 part, a rubber coated metal piece that snaps in place?

 

Not following you?

LMC truck shows an inside(#7) and an outside(#8) trim piece, I can't tell which one you want, so I listed both, but each is just 1 piece
Outside the glass and inside the glass

Outer left and outer right doors are different parts
As are inner left and right
