I mis-spoke(wrote), here is the details on the gear I used; copied from the Reactor thread on the 3D forum.
FWIW I used the Graphtech 120 #120 Hangar 9 33%/35% Extra 330 Main Landing Gear on my Reactor, I simply cut the gear down the center, used the originals to get the hole spacing correct and mounted them up. I also had to open the slots in the fuselage about an eighth of an inch. They work great, look pretty cool too. Cost me all of $35 on sale a couple of months ago. No more prop strikes during my less than graceful Harrier arrivals
