I have bought two pair of rear tail lamp lenses (repo) that have not really matched up with the o/e "guide" 69 lenses. Are there any good repo's available or any "nos" around? Can you suggest a source and appx. price I should expect to pay ? I am looking for non rs type (standard).

There was some NOS lenses on ebay.

Also, 69 non-RS lenses are pretty common. You should be able to find a good pair.
