No problem, 356 was one of the first Jags I ever worked on so it sticks in my memory. If you really want to go to town you could modify the tailcone to make it a hinged one as by this time most if not all ac had this modification (I think photos show it on 356). It's fairly simple to do, you need to take about 3mm from the very end of the cone, fill it and slightly round off the edges. Then on the lower surface of the heatshield there should be a small thin fairing about 5 to 6mm long (IIRC) that would have housed the spring actuator for the tailcone. This detail is often missed on models of Jags from the mid 1980s onwards. All dimensions are actual for 1/72 scale.
Hope this helps
