As I mentioned in the review of the basic set, Cutting Edge has provided separate conversion bits for the kit that you are using. In this case, the set is for the F-4J kit by Tamiya. Included in this set are unslotted stabilizers without the reinforcement as used on the early F-4Bs. You also get a replacement radome and the early IR sensor pod. Since the F-4B was a bit longer in the fuselage around the burner cans, there are extensions for that area as well. You bascially cut out the short ones and put these in their place. As all the cutting is on the panel line (something that Cutting Edge tries to do with all their sets), it is not as difficult as you'd think.  I'll repeat that you do need to have set CEC 32180 to use in conjunction with this one.

Like the earlier set, the instructions are very comprehensive and provide all the information you need to use this set. There are also large color photos to help you get everything just right. I know I've said it before, but Cutting Edge resin products are among the best you can get anywhere. The molding is crisp and clean with parts relatively easy to remove from the pour sections using little more than a sharp hobby knife.

If you can't find Cutting Edge products at your local hobby shop, you can order direct from the link below.
