wheel adapter help

[powerline84]

i just ordered centerline smoothies in
20x8.5 5.4 backspacing rear
18x8 5.0 backspacing front
I have a 1970 longbed and i want to order some wheel spacers for it. I need some help on thickness with the spacers what thickness should i get?

also the guy who is making them needs the measurement of the hub (hubcentric)to make the spacers, can someone give me that measurement?

thanks for the help

these should work right. 1" spacers.

;;These bolt-on wheel spacers are designed to give you a little more width without changing out your axle for a wider one. Features safety graded studs and matching nuts for proper fit. Spacers are 1.25" and 1.5" thick. Made from Billet 6061-T6 aluminum. Grade 8 Studs, Grade 10.9 nuts. Only high quality nuts and studs that are hardness graded and stamped are used. Spacers feature precision machined surfaces for proper fit and contact with wheels and hubs.

I'm looking for the same thing, only for an eight lug rim.
Anyone know of any?

Ive used them on my truck. 1.5 in the rear and front. They have been on there for about 4 years now with no problems. Some people will comment on how it adds stress to the axel. The backspacing doesn't really add any stress, think of it as just adding more backspacing to your wheels. What is does affect though is that you will have more dynamic weight, especially with the weight of the larger wheels that you will have to stop. That will affect your braking efficiency.
