anyone know the front door speaker size of a 2wd sierra cos? I am looking to get mine upgraded but dont want to strip the door down yet!

 

I've got the old ones I took out of my 2wd, I could measure but pretty sure they are not std ford items, they're jensen make, but had adaptors so I souhld be able to see the oe size.
I fitted JBL 928 GTS speakers, cutting the front door cards to fit, well worth it, just need to do the rears now.
