American mates,
Can someone please tell me what type of stud pattern configuration my 1967 Delta 88 would have ?
One person told me it's called "5 x 5", another said "5 x 4.75" ?

and then there is a guy on Ebay selling a set of Rally wheels that says in his ad that they suit Delta but then says not "88" !

How do I know what it is ? How do you measure it ?

Oh yeah ... would a 66 Delta 88 2 door be the same pattern ?

Thanks in advance

 

My guess would be 5 on 5.
Next time you are on Ebay do a search for Bolt pattern gauge. Pick one up for a few dollars.

thank you both !

 

I believe J is correct. The late 60s Deltas were 5 x 5, just a hair bigger than the 5 x 4.75.

 

Please check out this and tell me ... do these normally fit ?

They wont fit....they are for a 4.75 bolt pattern car....you have a 5 inch bolt pattern.

 

I have a 1968 Delta 88 and I'm trying to change the front in off what would be the best fit

 

Eric, your Delta 88 has the 5x5" bolt pattern. The only Oldsmobile wheel that will fit besides the OE one is the SSIV. Regular SS wheels have 5x4.75" bolt pattern. If you want aftermarket rims look for a 15X7 wheel with 4" back spacing and 0mm offset. Here's a pic of my 71 with Eagle Alloys (post #24):

Here are numerous posts with pics of the Olds SSIV.
