1 17/32" is very close to 1 1/2".

I would start at Drumfactory and try to find 1 1/2" Center to Center hole space lugs.

File holes just a little bit to fit.

Perhaps they also have BD lugs at 3 3/8 C to C.

10 Superstar BD Lugs on Ebay $50.00

I am building a seriously abused '77 Imperialstar set right now. One of the BD lugs had broken pegs.A screw won't hold it on now. I went through my junk pile and found a 2000's Rockstar BD lug, and the hole pattern is the same. You can probably buy a whole Rockstar set on C/L for the cost of the vintage lugs and bolt them on.I'd even say most if not all Tama lugs are going to be the same hole spacing. I see mid-grade Tama sets used on C/L for very cheap money.

Thanks for the help! Much appreciated.

any update on this? I'm currently building a beater kit out of some unused 80s Superstar drums (18" floortom will be the bass drum). Do the RS lugs fit the same? thanks!

Of all the 1980's and probably early 1990's Tama bass drums used the same hole spacing....Superstar, Imperialstar, Royalstar, Swingstar, Rockstar.

The bass drum lugs might be approx 3" long.....but the whole spacing is 2-3/8" and that's what counts.

Distressed Imperialstar kits are one way to find cheap parts for a Superstar kit. You can sometimes buy a 4 pc shell pack of Imperialstars for $200. Bass drums alone can be bought for $90-$110....and they have $200-$275 in parts on them.

For those of you robbing Imperialstar drums, I would be interested in any Midnight Blue shells leftover...
