An alternative source part in USA for steering rack gaiters/boots.

I'm not sure how many USA based folks are on the forum, but I found Beck/Arnley 103-3070 Steering Rack Boot Kit will work for you. Somehow a review on Amazon was posted and that reviewer put it on his TR7. Since the TR7, Stag and a few other Triumphs share a common boot, I'd thought I'd try one.
I can't see where it is made, but the name behind it is stellar.

I made a short video here: https://youtu.be/uq9SLSVZSZs

Good find Sujit - looks like this part in US made in TN, so with luck the formulation of the rubber compound will be fit for purpose and they'll last well.
