This is what you have to do when you realize too late that the stock kit had a very unauthentic frame assembly and you have to scratch-build the missing components after you already have the engine and suspension in place. I did experiment with building and the subframe before mounting the engine (like a real car!), but the engine wouldn’t clear the firewall.
For those of you considering modifying the Revell or Monogram 1/8 scale Jaguar, talk to me! For the most part, it’s a pretty good kit, but many of the parts and subassemblies are toylike in design. I’m really becoming a proponent of building a kit twice, especially if you’re planning mods–once without painting to familiarize yourself with the stock models idiosyncrasies so that you can plan your build, and then the actual painted build. For this build, I had to really go against the order of assembly laid out in the instructions.
One other recommendation: Don’t be like me, and make it up as you go! Settle on the car you want to model and the level of detail you want include, then stick to the plan. I’ve always been impatient and too in a hurry to dive into a project, and I pay for it with a lot of rework.
