I had these header seals made for the A/A Pro 21 engines I have been expecting for the past 4 years.
The seals have the inner rib for Rossi and NovaRossi 21 engines. However, in the photo you can see thay they fit the MAC 21 exhaust stub as well.
Available from Roger Hooks Sr., Stumpfab, or direct from A/A Products at $3.00 per seal in single packs, or $9.00 in packs of 3 seals, plus shipping.
