Re: Wrong offset on rear wheels?? I ordered boss 338 20x10 rears 18x8 fronts

The rear 20x10's only come in one offset.
(6.225" backspace)
Did you try them on your truck to see what they looked like?
Most likely you will need a 1" or 1.250" spacer.
These wheels were designed for the 88-98 trucks in mind.
I assume you know all the problems related to the front wheels not fitting?

This is the best I have that shows the lip. They have some lip but not what it sounds like your looking for.



lolife99 is right. There are two loonnggg threads about putting these on 67-72's. They don't just bolt on.

I did not pick-up the wheels. Yes, Same thing I thought only one offset offered.. The part number right off of bossmotorsports.com is 3386-2050 / 20x10 5 on 5 20mm / 6.225. my only problem is Discount sent the wheels out to be chromed and they did not come back in the original box with the part number. I am thinking Boss sent a different part number. This is why I was hoping some one will post a picture reflecting this part number.. Thanks for your help...
