1974 Kawasaki Z1-900 & 1974 Kawasaki Z1-900 Barn Find

We are hoping to be able to pass these bikes and all parts along to someone who needs them or is willing to restore the bikes back to their original glory.
These bikes and parts are being sold as one package, we will NOT be separating or parting anything out separately. So the successful buyer will be getting everything shown in the photos and will be responsible for taking everything! Also, both engines on these bikes are not stuck and have compression.
Please note that the 1974 Z1 has a 1015cc cylinder (see photo). Please keep in mind these bikes are 50 years old, many of these parts are also the same age!
PAYMENT: A $500.00 DEPOSIT is due within 48 hours. The balance is due in full within 7 days. The bikes/parts cannot leave our premises until all funds have been fully transferred/deposited/cleared.
SHIPPING: THIS SALE IS FOR LOCAL PICK UP ONLY. Please note that the buyer will be responsible for all shipping requirements/costs from Merritt Island, Florida including the selection of the shipper.
CLARIFICATION/UPDATE: We were told by the previous owner that these bikes were a 1974 (Brown one w/title) and a 1973 (Blue one w/o title). After doing more research on the frame and engine numbers, it appears that the Blue one is NOT a 1973 Z1, it is also a 1974 Z1. Here are the VIN#'s and ENGINE #'s:
1) 1974 Z1 (Brown Bike) Frame & Title VIN# Z1F28487, Engine# Z1E28622.
2) 1974 (not 1973) Z1 (Dark Blue No Title) Frame# Z1F44426, Engine# Z1E044555.
Please do not hesitate to ask any other questions or share any concerns.
Thank you for looking!
