Hi Jay,
I'd love to come over and see your new treasure in person, but I'm out of town for a few months. In the meantime, I suggest you look up the local club, maybe attend a few meetings and events. You don't have to join, and everyone will be glad to see you (and your car). There are some very knowledgeable club members, some even do restoration work in their spare time (if, for example, you want to replace that drippy rear main seal, but lack time and tools, etc to do it yourself).
The main meetings are usually the 2nd Wednesday of every month, at Carrows in Rosemead. You can find more details on the club website at

(The club has been recently renamed to Triumph Club of Southern California; but they are still using the old Southern California Triumph Owners Association web site.)
I highly recommend the "Drive on the Edge" event, happening this Saturday. Nice leisurely drive (within the posted speed limits unfortunately) through the Angeles National Forest, with a bunch of other Triumphs. Flyer at

If you feel that is a little too ambitious for your new acquisition, "run what you brung". You'll get relegated to the back of the pack, but still welcomed to the event. In the past, we've had Miatas, MGs, even Volvo sedans show up. Still a nice drive, great scenery is always improved by following a line of Triumphs
PS, this isn't really the time or place, but since you mentioned "marking it's spot", I want to explain that there are two major upgrades available for the rear main seal. Of the two, I strongly recommend the "Mad Marx" (aka Viton) version sold by Roadster Factory and BPNW. Unlike the one Moss sells, it does not require machining the crankshaft (so no worries about it being machined wrong), and actually keeps the original scroll-type seal functional. The Moss unit can be made to work, but often leaks even worse than a worn-out original seal! One of our local club members actually sold her TR3, in part because the seal conversion went from a few drops in her garage, to a steady trail wherever she went.

PPS, I maintain a modest collection of Triumph-related documents at

You might find some of them useful. I recommend that you download anything you find interesting, but I do occasionally made updates and additions, so check back from time to time.
