Any tips on where to buy parts?

I am attempting to fix the touchy throttle issue and wanting to buy the
04000-0440C
Accelerator Pedal Assembly part I've seen recommended in several threads.
But my local Toyota dealership says that is a recall part only and they cannot sell it to me.
I've found it online at a few sites but not sure how legit they are. Any suggestions on where to buy?
(Getting ready to hand it down to our 16 y/o son and he's not loving the express pedal action.)

TIA

 

If you.google that part number, there are many dealerships that sell it.

 

I have tried that, they show unavailable when I go to order. The only place I can find are on 3rd party sites and I'm not sure who is legit and who isn't.

 

I'll check with my buddy that's in the parts department and see what he can find out about availability.

 

Looking to stock up on Toyota oil filters for my '18 5.7. Would Sparks be the best deal for bulk?

I'm also looking at OEM Denso 3421 plugs and am seeing RockAuto has the best price at $6.64ea. Any suggestions on these?

Thank you

 

For the filters, your local dealer. Sparks will get you on shipping.
