I checked the interior space with the seat in place. It was far too short for a driver to sit in it. So I cut through the body just aft of the scuttle and lengthened the body by 8mm The joint was filled with plastic card and slathered in plastic soup. This extension made the cut-outs too long so the rear section has plastic card built up and slathered in p/s for re-profiling.
I'm adding to and re-profiling the seat's centre arm rest as well.
The scuttle is too short, so plastic card in strips and bits was glued on to extend it backwards by about 5mm. It too got a generous coating of p/s;
I like using plastic soup on changes like this as the solvent in it makes the p/s and the model plastic meld together. Its a chemical bond rather than a physical which you get with some other fillers. P/s is cheap to make and handy to keep on the modelling work bench. The runny nature of it means it can flow into gaps or voids, and if its thick enough it can bridge gaps.
I came across this photo of a 1907 or 1908 'sports' car;
Hopefully my car will be a bit better looking.
