Thanks for this Martyn. Really useful video and top marks to Gold Star.
I'm struggling to find the actual part number based on the one I already have in my 3.0 Alphard which is 063700-8590 (based on the pic)
On eBay there are plenty of Avensis ones with part numbers ending in 8580 or 8610. Was hoping to do a swap of the whole part but not sure if I specifically need 8590.
