Yes, P1 V70 upper lights will fit but you do lose the amber lense of the 850 and thus have to use an amber bulb. No biggie, works perfectly fine and some people prefer it as an upgrade but if you're looking to retain originality, then V70 items are no good as far as the cosmetics are concerned. 850 units are hard to get these days, more so as they tend to fade / tarnish with age so finding good, original ones is difficult and / or expensive, relatively speaking.
