We love to see owners enjoying our Z Car Garage CV Axles in their vintage Nissans and Datsuns. This 1971 Datsun 510 is owned by Jay W and he replaced his old CV Axle kit with our ZCG CV Axles just over 3 years ago. Jay has been racking up the miles running numerous road rallyes in 2024 and 2025 including the Snowball Rally in April, DWA Classic in May, Motherlode 400 in June, Faultline 500, Tokyo Calling 4 in September, Socal TT in October. Here is his report from the Overcrest Rally.

2024 Overcrest Rally Redux

September 16, 2024, by Jay Whalen
Hi Rob, just checking in as my ZCG CV Axles #403 just clocked 20000 miles in 2+ years. I didn’t capture too many driving videos on Overcrest, but my wife and I have a few from Mother Lode and Faultline this summer. Also, we now have ~22,500 miles on the ZCG axles. Don’t worry I’m cleaning them up, but here are some recent pictures:


The opportunity to enjoy a car you love with like-minded enthusiasts against stunning natural backdrops is what I appreciate most about rallies. The adventure, camaraderie and community stands out to me about Overcrest and was evident when we drove in the Oregon 23’ rally. At their film festival in Oregon they announced the spring Redux 24’ rally was in Utah and I knew I needed to share the adventure with my father and son in my 1971 Datsun 510. I had followed online the 21’ Overcrest Rally in Utah I was blown away by the stunning backdrop and the cinematic journey the rally created. Plus seeing and driving with rally friends, I didn’t know were attending and meeting new ones from all over the country is a large reason I’m drawn to Overcrest.

The 510 is not just a mode of transportation for the rally; it’s a character in my family’s adventure story. There is a shared excitement of revving its underpowered engine, hearing the twin Mikuni carbs, and dancing the car on winding paved and dirt roads. There is also the collaborative effort required to navigate the rally route, endure hundreds of miles a day of hard driving and the collective pride in showcasing our classic amidst a field of diverse vehicles.


Speaking of diverse vehicles, our client Tony K also attended in his 1972 Datsun 240Z:

joy of driving.


Our rally journey took us 8 days and 2900 miles across the California Centra Valley, Sierra Nevada, Movaje Desert, Great Basin and the Colorado Plateau. We drove a large loop which allowed us to explore several National Parks and retrace my fathers HWY 50 drive when he moved to California in 1971. The 510 did extremely well, with no major issues. We had a flakey starter motor, wore out a pair of tires and went through a quart of oil.


In essence, the Overcrest Rally in Utah with my father and son was a celebration of heritage, a journey through time, and an opportunity to weave new memories into the fabric of our family’s motoring legacy.
