Thanks for the info everyone. Just to know the 69 280 conquered the wee grade without a hitch. After 350 miles of 70-75 mile per hour driving from Nor Cal I approached the grade at dusk with some concern. Needless to say the little sl easily made the grade and at one point, behind a slower driver down shifted to 3rd, changed lanes, and the car easily climbed it at 45-4600 rpm and over the crest. The temp gauge sat just above 180 degrees F for the ride down from nor cal on the 5 and at the hottest on the grade right at 190. It just goes to show us that our cars were good from coast to coast travel back when new and quite frankly, based on my american muscle car experience, if the US manufacturers cars of the 60's can still get me 2000 miles away and back, these engineering marvels should be able to do it twice!
Cheers and have peace of mind in a well cared for machine.
I posted a pic of the son of the original owner handing me the keys. George is a wonderful man and his mom owned this car since new in 69 until she died about 5 years ago. The car has all the original docs and equipment so if anyone needs details on items for reference let me know and I can snap a photo and send it over including the orignal spare with the curb rib and notations " For US Cars Only" I removed the original west german trunk light this morning and replaced it with one for a 67 Camaro.
