Topgun24,

I checked my F-15 pipe mounts and they fit fine, you may need to sand the IDs a bit to get it to fit or email them with the pipe od dimension, and I am sure they will replace it for you. I also looked at the fin installation, I beleive there are some wheel collars in the hardware bag that can be used to secure the fin in place. I did not check my bag of hardware, but I really do not see any other way unless you epoxy/hysol it down.

I have not satrted the F-15 yet, I was almost done with my F-16 till I saw Joe's photos where he used an aluminum cover in place of the fiberglass piece that goes on the end of the semi bypass. I like his Idea and will make the same mod (Thanks Joe).

Regards,
Mike
