One supplier I can heartily recommend is T.D.Fitchett. They are a bit "old school" in that they don't have a website (one of my young TSSC friends said he would offer do a website for them) and the bloke that answers the phone comes across as a "Mr. Grumpy" but once you get past his demeanour it is great. They know their stuff, they accept plastic and your order comes in the post the next working day by Royal Fail. I've never had any issues with quality and their prices are competitive. They advertise in the classic car mags so you should be able to track them down without too much difficulty.
This forum should be the first place in your search for a Sprint. My last 2 Dolomites (a Sprint and Brown) were sourced via here. Other places to try are eBay (you MUST view the car before bidding - I viewed my Dolomite 1300 which had been listed and ended up buying it privately.), Triumph World, Classic Car Weekly, Classic Car Buyer and the other classic car mags.
I second what has been said by Julian (tinweevil) about the cooling system. There's nothing wrong with having an electric cooling fan (modern cars have them) but the cooling system needs to be in tip top condition in the first place rather than it masking a problem. I run Brown with a 50/50 mixture of blue antifreeze. I know some on here would say that 50% is too high but I keep it below 50% and top up with water which shouldn't dilute it too much. The last time I drained Brown's cooling system the coolant was still clean despite a 2 year lay-up in my unheated garage so I reckon I'm doing something right. Aside from a collapsed heater hose I've had no issues with Brown's cooling system and my Sprint didn't have any problems either apart from the fan trying to bury itself in the radiator.
My "Project Brown" thread is another thread you should look at. Most of the 1850 stuff applies to the Sprint as well.
Good luck in your search.
