Correct spacers needed????

Im looking to put some rims on my 86 silverado (5x5). Here are the specs.

Bolt Pattern: 5x120

Hardware:14x1.50 Lug
Offset:
Front: 30-40mm

Can anyone recomend the correct spacers and possibly a brand?

Re: Correct spacers needed????

5x120mm wheels would not work...they need to be 5x127mm=5x5

Or are you asking about adpters(to change bolt pattern)

Or spacers to move them out some?

Offset means nothing unless you know the rim width.

Re: Correct spacers needed????

Sorry I should have done a better job wording it. I need adapters with the correct back spacing.

I'm having a hard time understanding any of your questions.

1) what size wheels?

2) exact offset?
30-40 mm is a range.
It's either 30 mm or 40 mm. Not both.

3)Is your truck stock height or lowered?
How low?

That's alot of backspacing on wheels for these old trucks.
I would think a 1" adapter for the front wheels and a 2" adapter for the rear wheels.

The best way to measure would be to "mock up" the wheels and measure how much they need to move outward.
