Can anyone provide details on a good auto parts supply store? I am specifically looking for a digital speedometer/tachometer similar to the photo.

For those type of items if you desire something more like a one stop shop AutoBachs is good if not a bit expensive.. Otherwise there are several places like Worachak in downtown BKK China town district that have a wide selection but you have to walk and shop..

At any rate can't say you'd get exactly THAT setup without quite a bit of searching unless you opt for an online purchase which is an option to consider.

Thanks WarpSpeed. Tried Autobac. No luck. I will likely order online instead but had hoped to find someplace in Thailand.

Glad to help sorry you couldn't locate what you're looking for.

Well, there is an online store called Autopartsfair.com,
where you can get all sorts of auto parts at your doorstep by just ordering
your desired one via phone call or by visiting their site.

You can find spares for nearly any car by just
entering the brand and model and all these are coupled with warranty and at a much
competitive price. Just have a look at them and grab the best deal.

"Nearly any car" provided it is a US market model

Nekketsu Racing have probably the biggest range of this type of thing: http://www.nekketsu-racing.com/www/store/category.php?category_id_o=15&subcategory_id_o=0&subcategory_id1_o=0
