Those who have hunted will know, finding a towbar for a the 2008 onwards Vellfire / Alphard isn't easy.
You can order a "Suntrex Tugmaster" towbar from Japan, but they are best part of £600, plus shipping (£200), plus duty and VAT.... its over £1000 to your door
Or you could fabricate something from scratch if you are that way inclined.
But what I found was the Lexus RX300-400h tow bar from Witter is nearly a direct fit, but some modification are required. Part number TY135BU
First the main beam across the back is 1090mm long, and it needs to be reduced to 990mm end to end.
Simply measure 50mm from each end, mark it very accurately, then slice it with a slitting disc.
Clean up the end plates and re-weld them back on.
Then I made up two flat plates to sit on the inside of the boot floor to act as a load spreader.
And 6 spacer collars I made from some 20mm steel bar, that I drilled out with a 12mm bore for the M12x125mm bolts. These need to be exactly 81mm long. I made them on a lathe.
If you do nice job of it, you end up with a towbar that looks straight out of the factory, with a branded e11 type aproval sticker on it 😂
Strangely, one of the bolt holes lines up perfectly with one of the factory holes and floor indentations. You only need to drill a couple of holes for the bolts. Spare wheel still fits perfectly. All looks like a proper one, whatever that might be.
Keep in mind the photos are mostly during the mock up fitting so the bolts haven't been tightened up.
