Default New Oil ring seems to be too wide for the groove!
Hi all,
I am rebuilding my '61 GMC 1/2 ton 305E v6 engine. Started to install the oil rings first and the expnsion ring is too wide to seat into the bottom groove, even without the wiper rings installed. Compression rings (all 3) fit well. I got the rings from EGGE Pistons. Went to the Mfg.(Grant) web page and the P/N is correct for a 305 V6.
Has anyone on the list had this issue? Suggestions welcome!

Thanks,
Glenn
