They usually take the order and payment, and then email back "oops sorry ..." . Bit like Allcarpartsfast/Endon often do.
Tried two items in the past without success. Refund went OK though.
Still worth a try perhaps?
Pity the pages never show the MGR part-number alongside the description.
That page looks to be specifically for "Automatics", if I read it correctly.
Be aware though that the two ball-and-socket ends I bought from a UK supplier to repair my gear selector rod, which normally cost £3.50 in total delivered in the UK, have finally cost me £23 with postage, customs fees, 2xVAT and administration costs to NL, post-Brexit. Any goods you may order in the UK from the EU may well result in similar daylight robbery thanks to the "seamless movement of goods" agreement, I imagine.
