Replace 4 rings (~20/55) with 4 50/55 rings. Replace thick wall BT-20 with an 18 inch long BT-50. Add a 20/50 ring for a 24mm thrust ring. Use 3/16" diameter launch lugs instead of the 1/8" launch lugs.
And be careful of the dowel retention doohickey location. The original instructions position it incorrectly and it misses the dowel-legs.

If nobody has that I was hoping you might just happen to know how to go about this off the top of your head... I'll need to know exactly which parts I'll need to, and where to get them online (again, we have no local hobby shops anywhere near, and the closes ones do not have individual parts).
Gracias!
