Build time estimates [Feb 2025]

Brass/Black Model Ts

Our longstanding foundry (supplier) closed and all production was shifted to a neighboring foundry. Apparently many of the closed foundry's workers were ineligible for rehire by the new foundry due to more aggressive immigration enforcement and the union has no employees to provide. As of 2-20-25, we should receive castings in March 2025 and can resume production then.

In the interim, we have been working with our one-off foundry to have pattern boxes made and these are trickling in in smaller batches and we will produce what we can.

Model As 5-6 weeks

Heater cores ~6 weeks

Model A and 32 Ford Street rods 6 weeks

Common street rods ~12-15 weeks

Tricky customs & complicated restorations ~16 weeks months

We appreciate your patience as we continue to recruit and train new fabricators and manage the labor shortfall our country has been experiencing.
