In the process of bringing my 87 out of winter hibernation I cracked the nipple on the coolant reservoir cap. Now it just sucks air and won't draw coolant back into the block when it cools down. Local Toyota dealership has the part listed as no longer available and asking at other parts stores just brings about the 1000 yard stare. Has anyone found a good aftermarket coolant reservoir that also has provisions for attaching the BHG (coolant level) sensor? All the ones I found so far are really spiffy and all but I'd like to keep the birdcage light function.
