Source for large engine thruster bells

Hello

I was wondering if anyone has a source for “larger” thruster bells??? I’m looking to upgrade an old Pre-HG kit and I’m seeking Two (2) Thruster Bells larger then 15mm, say 20 to 25mm (15/16 inches). Thanks for any and all help forthcoming.

Ebay it a good source.

That’s probably the best place. Everywhere else online I shop at they’re always sold out

Look for the Bandai or Kotobukiya parts packs. There are several thruster and vernier packs out there.
