Looking for 1.5" extended rear bump stop extensions

As the title says, I'm looking for 1.5" extended rear bump stop extensions. I bought a Dobinsons MRR 3" lift with long travel rear shocks which require 1.5" extended rear bump stops.

I think Toyota makes em for their TRD lift kit (according to his video, Revere Overland put them on his 22" Tundra). Does anyone happen to know that part number? I know Icon has some rear bump stops, but I'm not sure if they're long enough. The only other ones I've found are from Timbren, but they're pricey.

 

I bought the front bumpstops from Perry for my Dobinsons 3”.

I didn’t go extended travel which I should have but I’m looking at purchasing rears.
