As much as I admire what you have taken on.
As I said earlier plenty of measurements available in manual so shouldn’t be a problem for getting stuff in the right place and square, plus you have old chassis still to double check.
But. Are you thinking of selling in the future?
In which case it might be difficult. Also your points system for keeping reg only just gets it for DVLA rules points
If you can prove the rest is original. The chassis is 5 points if I remember. (Or are you just not going to tell
)
Sorry just sensitive to numbers especially on LRs, absolutely nothing to do with your ability or want todo.
