Dave, like I said above the early thin centre ones were dangerous. I think there was a recall back then but some may still be about.
I'd only use them on a trailer queen.

They are from a guy who has an early (English import??) 850 who is restoring it and I have the wheels to paint for him. Car not going atm.
Markings on each rim are:
"350 BFL - 10"
On the nut side there is a mark "8K"
The centre bit thickness measures at 0.125 or 1/8"
Interestingly the rivets are not equal distance apart. Each of the five wheels have the distance between the two rivets anywhere from 1.2" - 1.6"
Will pass on the advice about the recall

If the centres are 1/8" then they are the thick centres and are ok.
1/8" = 11 gauge.
3/32" = 13 gauge.
