Hi there! I'm looking to procure an adult shifter chassis for a project I'm working on. Could you please provide me with more details regarding the specifications, materials, and available options? Additionally, I'd appreciate info on pricing and lead times for production. It would be great if you could send over any relevant catalogs or documents that showcase your offerings in this category. I'm particularly interested in understanding the customization options, if available, to tailor the chassis to my specific needs. Thank you!
