Need to find a "sealing ring" - brass ring 274000152 for 95 Sportster

[r3cc0s]

Had the motor rebuilt bottom up - the current brass ring is leaking a "bit" not tons but enough to leak exhaust and some water.

Can't find this thing anywhere... any suggestions?

Is that the copper washer in the exhaust? If so, did you use high temp rtv?

no just clamped it back together - didn't see any silicone on it
