I would like to issue a warning on those spacers.
I used them on the front of my 76 when i decided to use 88 tbird rims for a while.the first night I had them on, I was coming home from work, the lug nuts stripped off the studs because there wasn't enough thread to hold.
needless to say I got lucky,and the wheel stayed under the fender.But what a mess! I was also lucky that I managed to slow down before it happened,when I noticed something was going wrong.
If you use spacers,make sure that you have enough stud thread to hold them.
Gluing them or epoxying them exactly centered wouldn't hurt either.
