Bolt Pattern?
Okay here'* the deal. My 89 sse has 16X7 wheels. All the guides say the bolt pattern for Bonnevilles is 5x115 but all the guides for 16X7 wheels say the bolt pattern is 5X120.7. Where do I go from here. Please don't tell me to measure it'* COLD outside.
Thanks
Richard

I wouldn't even risk that on my beater. And your wheels will have no value if you ever try to sell them. The misfit will be obvious.

i guess its how you drive and how careless you are. my rims still look new in the holes.. cant even tell they were used.. and when i put them on i cant feel any play at all what so ever..

You won't feel any 'play'. But your lugnuts are loading ONE single point in each countersink, instead of evenly distributing the load around the entire circumference of each hole.
I think most of us would prefer the peace of mind knowing that we have full-strength holding power that isn't point-loading every single hole. I don't want mis-fit wheels to affect how I LIKE to drive.
If you don't know what I mean, I can put up a graphical representation for you.

I look at it a little like this... With the 114.3 as opposed to the 115, you are loading the Hub studs to the inside which pulls on the outside of the stud face on the rear of the hub, when you have all 5 of the studs torqued you are side loading the studs, but to the inner circumference of the Hub/Wheel, you are not using the full strength of the Studs and are possibly weakening them to a certain degree as they are side loaded...
When you attach a 114.3 wheel to a 115 hub you are in essence pulling the stud in a direction it was not meant to go in... It may work and for a long period of time with no issues... But if you remove and install those wheel a few time you could have that stud snap or weaken over time... wouldn't be too fun to have a wheel pop off at 80 Mph..
When you use the 115 wheel with the 115 hub all of the studs will be loaded evenly around the circumference of the stud as opposed to being side loaded...
Make sense?

diagram time!
the 5x115 shows how the lugnut has direct contact with the wheel.
the 5x114.3 shows how the lugnut only has contact with the wheel in once place of the rim. If you are torquing down the lug far enough that it contact on all sides, then you are bending your wheel stud bolt!

And in the pic above, every stud is being BENT after tightening, pointing to a common point near the camera lens. All of them bent inward towards the hub centerline.
Anyone doing this better drive like my deceased grandmother drives. It'* caused countless problems on other internet forums. None here, because we've been preaching the warnings for 5 years.
