Marc,
I did quite a lot of work before trimming on making all this fit, pre-carpets as it were.
As you can see, my centre console had been botched at some point and I had to do some metalwork and fettling.
Bracing the radio console by the addition of that little angle-section at the rear made a massive difference to the ease with which it could be fitted ; tip -
don't bother fitting bigger speakers if you've this sort of console, complete waste of time.
My gearbox cover was lowered where the lever is to take advantage of the 5-speed gearbox's different shape - tho' this only makes the trim around the bezel and the gaiter easier to fit.
So I was able to "tailor" the width of the forked part of the Centre C to suit the Radio C, before getting both parts electro-plated.
You are quite right, however, to take all this quite seriously, and I had many problems when it all started to go back together - despite my best-laid plans - as I had underestimated the effect of the carpets on the tunnel.
These stopped the Centre C going as low as I had hoped, and was exacerbated by my addition of bituminous sound-deadening sheeting.
Eventually I had to cut back considerable parts of the thick underfelt around the tunnel so that the Centre C would go low enough and the Radio C far enough forward and downwards without bending the bottom cheeks.
Even now, perfect as it may appear, folding the dashboard down
just brings it into contact with the upper edges of the ash-tray panel, and it has nicked the leather at those points - I should have aimed to gain another couple of mm at that point.
You can't see it but it galls me that having spent so long - what, 50 hours messing around in this area ? - trying to get it right, that it still isn't ..............
I think we have to remember that many of us are aiming for standards of finish that were absolutely not present in the cars when they were new.
I ought to get out more often.
