C20 & C30(SRW) factory 8 lug Kelsey Hayes steelies ?

Can any ya'll 3/4 and 1 ton'rs tell me the difference b/n these factory Chevy 8 lug steel wheels ? One is 70's C20/C30 and the other is 90's G30 van. I thought they used the same wheel - does the van have a different offset ?

Honest injun Kelsey Hayes "KH 16 x 6 1/2" 8 lug steel wheels are getting tough to find.

While on the topic, how were the 89-93 Dodge 8 lug steelies different ? they sure look identical to the GMs - different hub/pilot hole dimension or were those 16x6" only ? Yeah I know all about the Ford 16x7 Accurides, but I'm only interested in info on the GM (& Dodge) wheels here.

Thanks

As far as I can tell those 2 wheels look alike. you can always ask them to measure the offset.
The Dodges have the same bolt pattern, I think the only difference is they might have 3 nubs for the hubcaps versus 4 for the GM and F#rd.
Just out of curiosity, do you already have a few 16 x 6.5s and that's why you don't want the F#rds??

It looks like the Dodges used the same KH wheel blanks for thier version then stamped a Chrysler Pentastar symbol between the lugs. I read they had both 6" wide and 6.5" wide versions, like the Ford Accurides.

Yeah, I want to match up and run a correct set of the genuine KH 16 x 6.5" GM steels and OEM 3/4 ton caps on a truck with LT255/75 or 265/75, and then keep a spare set of same rims on the shelf in case of bent rims etc.

I know the Ford Accurides are considered a little better quility and I like their extra 1/2" width, but I really prefer hub centric wheels, over lug centric. In my years experience, hub centric wheels balance out better with less wheel weights and cause less problems when rotating them.

...here's Dodge's version of the 8 lug 16x6.5" steely. I guess its application was actually mid-90's 1 ton vans. Ill have to see if I can dig up it's hub hole diameter and offset in the specs. GM's 8 lug 16x6.5" hub hole is 4 9/16" diameter;

EDIT:
Ok, looks like the;
* Dodge 90's 1 ton van 16x6.5" steelies have a 121.3mm hub center diameter.
* GM 70's/80's C20/C30/K20/K30 16x6.5" steelies have a 116.7mm hub center diameter.

* GM 70's/80's C20/C30/K20/K30 16x6.5" steelies have 116.7mm hub center diameter.

The Ford Accurides use a hub center diameter of 125mm.

Just the offsets to check now.

Re: C20 & C30(SRW) factory 8 lug Kelsey Hayes steelies ?

Got a question for any ya'll Hollander experts. Seems at some point over the past 20+ years, Hollander changed their assigned interchange number for the 1974-87 16x6.5, 8 lug steel wheels from 560-1055 ~to~ 560-8009 (A or B). Anyone know when and why they would've done that ? Nothing appears to have changed - same interchange models & years. I was also reminded the 8 lug 16" wheel was only 6" wide through 1973, then grew to 6.5" wide in 74.

For the novices, the Hollander Interchange guide is the "Junkyard bible" that every dismantling yard across the nation (possibly world ?) uses to identify and market specific auto parts for identification and resale.
