I will get some shots of my Competition and post them here for you.
As far as parts go, anything from the period that fits and pleases you should be ok, as they were sold as frame sets only.
I went a bit over the top with my restoration when it came to buying all the ancillary parts.
The reason for this was because I made myself a promise that one day I would add high end components because at the time I could only afford low end stuff. Of course, I never got around to doing it until nearly 50 years later! Oh well, better late than never!
I will try and get the photos up within the next few days for you.
