Esci Jagdpanzer IV Kit Bash

I've recently won a couple of old ESCI kits on eBay, both of which are Jagdpanzer IV so ideal for the Operation Blackcock project. I'm planning to kit bash these with the tracks from the Armourfast Panzer IV kit, in order to avoid having to build the whole chassis with its numerous fiddly wheels, especially as the old flexible polythene tracks look a bit rubbish. I may have to adapt the Armourfast track units with metal road wheels at the front end but I don't think anyone will be bothered, so will probably just use them as they are. I love these old ESCI kits as I used to make them when I was a kid and the original box art is pure nostalgia!
