美国采购需求：推土机零件

I'm looking for the pricing details for a couple of specific parts for a Komatsu dump truck. Could you please provide me with the cost for the yoke and the spider assembly? It would be helpful if you could include any available options or variations as well. Additionally, I'd appreciate it if you could let me know about the lead times for these parts and any bulk purchase discounts you might offer. Looking forward to your prompt response, as we need to make a decision soon! Thanks!
