These intakes are full depth, correct diameter replacements for the Hasegawa kit versions. They are virtually the same set as 48198 which features the PW F-100 PW-100 engines but these feature the later -22X versions for later jets and re engine jets.
I have included a couple of pictures that may help in assembly as they are not a simple drop in fit. Nothing very hard at all and they are similar to how the 48080 and 081 intakes fit into the GWH kit. Mostly thinning and test fitting.
