Well after getting the radiator and checking it the first one was bent, the second was was good, baffle in the top and so I jumped to it and put it in and 45mins later the job was all complete. No bleeding problem as used works vacuum filling machine. Ran her up needle just below half way no hard pipes and nearside rad top is warm and offside rad top is cool.
So a successful afternoon, I do prefer to work on the p38 rather than the new l405.
