Root is currently mute, again. They have clockwork telephones in the Cotswolds, allegedly.
The rear lights just might have been Reliant. Most survivors had them pulled off by the Ministry and replaced with a now obsolete unit used on various kit cars and trailers. So if you have a couple of sets of mounting holes, that is not uncommon, even a shaddow of one light supperimposed under another. If you want the genuine lights, its autojumble time. However the light was redesigned and appears as a trailer light with a number plate port in what would be the bottom on a Type 70. Not many would notice the difference if the number plate port was blanked out. My car is not here to quote the specifics.
The wipers are effectively as period BMC/BL
Several paint colours but laterly settled on one, applied inaccurately and to a poor standard of finish!
Mr Cyphus will probably have numbers etc. Barry, of this forum, might have the parts.
Be aware that the steel window frames on the doors rot at the base, front and back. They are not available. An early repair, if needed, will avoid a more difficult one later.
Many Type 70 have the friction material bonding fail, or seized drive pick up. Totally fixable but rather a job. If it refuses to 'drive' then that will be suspect. Pays to get some lub in early, in case spanners have to follow.
Root can copy a manual and notes, ex ministry.
I find most Type 70 have the timing set wrong. I think this is deliberate miss-tuning, as if set right the go like the clappers, 70 mph in the fast one (might be on larger cylinders. Styer Puch used up odd parts left over on the contract so not all engines are the same.....!)
