Lug pattern?

Is the lug pattern on a 79-87 chevy truck the 5 on 4 3/4 like our early chevy vans?

Full size Chevy trucks use a 5 on 5 pattern. Vans from the 70's use this as well. S-10's and most cars use 5 on 4 3/4 pattern.

Thanks Duane !!!! Thought I'd found a buy on a set of Cragars but if that's the case they won't fit.

Here ya go Mike:

Thanks Dan. I found that last night but wasn't sure about the MM thing. Found a converter this morning and now I know.

120.7 mm = 4 3/4 inches

127.0 mm = 5 inches

The guy told me on the phone that they were 5 on 4 3/4 but he also said that they fit 79-87 chevy pickup. According to the chart and Duane the 79-87 pickup is 5 on 5. Since their 500 miles from me I don't think I'm going to chance it.

Mike, You might want to verify that the truck is a "Full size" since S10/S15 truck from 1982-on had 4 3/4 pattern.
