MR2 and Celica dipsticks are indeed different -- not interchangeable without pulling the pan and changing the pressed in tube in the block, and then the Celica alternator location gets in the way of the MR2 disptick without customization. If anyone in the PacNW needs parts, I've got a little bit of many different things used in my used parts room. Give me a call if you are trying to find something for your 3SGTE as I may have it. If it's available new from Toyota, we sell most new items at 18% off list price for Toyota OEM Parts.
