Little Olds specific info, but lots of tech info. Wheel crossover chart by bolt number and spacing, axle widths, auto math, etc. Look at tech and tool section.http://www.roadkillcustoms.com

 

Well, their wheel bolt pattern cross reference chart isn't even correct for Cutlass.


Search on the RWD Cutlass and all you get is that 1965-87 use the 5 x 4.75 bolt pattern. Actually, it should be 1964-1988 that use that pattern, and it also overlooks the 1961-63 cars with the 4 x 4.5 pattern.

I've found that nearly all of these on-line all-encompassing wheel bolt pattern charts have errors.

 

Thanks Joe. I found the site while looking for a simple thickness chart and measurements for sheet metal and wire gauges. Then I noticed the wheel chart, and looked at the 5 on 5 wheels. I usually always try to check more then one source on any info on the net before I commit cash.
Any comments on the 5 on 5 info?

 

Based on a quick glance, it's a mess. For example, it shows that the same years for Caprice in the 90s came with metric studs but shows SAE studs on the wagons. The list is not correct for Caddys (only goes back to 1986). It only goes back to 1964 on Buicks and Oldsmobiles. There's a lot more, but I've lost interest.

Suffice to say that the list is far from comprehensive and has some details wrong or overlooked.
