I'm looking for a cylinder liner repair kit suitable for a certain heavy-duty engine model. Can you let me know if you have this item available in your inventory? Additionally, if you do, could you provide details on the specifications, pricing, and lead times for delivery? Also, if you have any alternative options or recommendations that might meet my needs, I'd be keen to hear about those too. Your prompt response would be greatly appreciated as I'm looking to finalize this purchase soon. Thanks!
