factory lugnut/stud size for 88 suburban. and spacer question

[shady]

I believe They are 7/16"x20 rh. but summit says 1/2" and another site told me 1/2". I just need to be sure so I can order more. Also I have found a bunch of 1.5" spacers in the right bolt pattern for my rear wheels, but they all have 14mmx1.5 studs. Do any have factory size. If not does anyone know the correct size to drill out to, to swap the fronts to 14mm. I dont really want to have 2 sizes of lugnuts on my truck.

BUrbs can be 5, 6, 06 8 lug. That makes a difference on which size stud you have. Which pattern is yours?

Also these rigs can be converted to metric lug nuts to run newer model rims where the center cap is retained by the plastis nuts. SOmeone here did it to a very pretty red BUrb.

6x5.5" I'd like to change lugs anyway to go a little bigger and maybe a tad longer. stock ones look too small
I just dont want to right now.

You are right ,they are 7/16s.

A change to 1/2 would be a great idea.
