I may have missed some threads here but when it comes to chassis repairs or replacement, please remember we have Spyder Cars here in the UK - they blasted, cut off and rebuilt the whole front section, replaced the integral heater pipes and painted my chassis at a cost which I personally found attractive, (in comparison to alternatives), and I opted to go this route. The end result was very impressive. (I don't believe our friends across the water have this option)
I have posted pictures historically of this on the forum but if you cannot locate them I am happy to post again for you - let me know.
Note: I am in Shrewsbury so if you are ever down this part of the world pm me and you are welcome to come and see for yourself.
