Libre Wheel Designs Compared

By Eric Neyerlin November 6, 2016

Libre Wheel Design History American Racing vs non branded designs compared Originally published on ZPARTS.COM HTML legacy site February 15, 2005 Red arrows point to features that differ or are dissimilar on Libre style wheels produced by American Racing Equipment brand and a wheel with no brand name stamped on it. Long arrow to lower backside area shows where ARE cast in raised letter text "American Racing Equipment". No name wheel has only barely visible "14x5.5" cast in letters and "71700" hard stamped into cast lip area. Initial reports I have from two knowledgeable early era

Early 240Z front brake baffle design

By Eric Neyerlin November 3, 2016

Thought I'd take a moment to share with others a shot I took today of a pair of very early Series One 240Z brake baffle plates that I am in the process of restoring for sale at ZPARTS.COM These baffles (RH 41151-E4100 & LH 41161-E4100) have a much larger brake cooling inlet duct opening than later design used on most S30 models after May 1970. Kind of rare to run across this unique looking duct. May add better photos later on showing a comparison of inlet opening size to that of the later design. Tables below will show you the critical production date changes of different de

Refurbishing Weber Air Horns

By Eric Neyerlin November 2, 2016

Does stainless steel rust? You betcha! Before I went shopping for one of those fancy looking stainless steel clad Weber BBQs last summer it had never crossed my mind that stainless steel, or at least certain types, could rust? Then I started reading those "honest Abe" Amazon reviews on BBQs. Review after review were going on and on about how buyers purchasing lifetime investments in a gorgeous looking, stainless steel clad, multi burner, whiz bang BBQs had theirs turn into "rust buckets" of sorts, after only a year or two of being stored covered and outdoors during the winter sea

Bitching Betty – what’s inside?

By Eric Neyerlin October 19, 2016

"Bitching Betty" ........... ever heard of her? Many Z'ers may have not, but if you are into 280ZX or Maxima models from the 80s, it's more likely you have? She's often referred to as a piece of "Automotive History", so I finally got to thinking, "Is there a Bitching Betty right under my nose, but I've never noticed her?" With that pressing question wandering about in my mind, a couple of weeks ago I was inventorying a bunch of mysterious (to me) electronic gizmos and gadgets pulled from 280ZX cars back in 2004 and what should I find........? Yup, there she wa

Stop & Tail Light Sensor Detail

By Eric Neyerlin October 9, 2016

Bet some of you die hard Z'ers have often wondered, "What does the inside of some of those countless ZX model electrical gizmos look like, such as a 280ZX Stop & Tail Light Sensor?" Thought you'd never ask, ......but since you have, above photo may partiallly satisfy your craving? Took it this afternoon while inventorying a large box of 280ZX electrical devices pulled from a 1983 280ZX several years ago that never got properly filed away to correct parts warehouse locations. Shot kinda reminds me of a miniature city of skyscrapers, power plants and city streets all aglow. Circuit

280ZX Marker Light Components

By Eric Neyerlin October 8, 2016

After 30 years of parting out Z cars and collecting vintage parts the contrast of how a similar part has evolved in construction and improvement from one model series to the next, often catches arouses my interest to study the intelligence (or lack of!) and economics related to these parts as well as to keep myself up to date on later model parts. This morning I found myself disassembling the relatively simple constructed marker lights from a 280Zx trying to clarify what components might be or not be interchangeable from front to back or side to side. I do this often because years of

RPM to Transmission Ratios

By Eric Neyerlin October 2, 2016

To my remembrance, back in 2001 Jeff Mischel created a RPM to Transmission Ratio spreadsheet that he shared with the greater Z car enthusiast community on Pete Springer's long gone GeoCities site which I saved for later reference. Today, I happened upon a stylized HTML conversion test of Jeff Mischel's original data and thought it could be of some use to current day Z car owners, so I've published as a reference page under the RESOURCES menu titled "Z Car RPM to Transmission Ratios" Hopefully, at later date, I can restyle the data with a more printable color scheme. Note: If a

240Z Headlight-Wiper Switch Identification

By Eric Neyerlin May 6, 2016

240Z Headlight-Wiper Switch Identification To reduce the confusion for many contacting ZPARTS.COM for a used replacement headlight/wiper switch for a 240Z model in this blog post I have published both a visual ID photo of all switch types I have currently in my inventory and a chart showing how many times Nissan changed the switch on just 240Z models from 1969 to July of 1973. To date I can't claim to be able to discern the differences, if any, between some of the switches with differing or superseded part numbers, but after carefully going through tens up tens of used switches in my in

S30 Stub Axle Components

By Eric Neyerlin March 30, 2016

Stub Axle Components Illustrated If your S30 model stub axle breaks or you damage or loose parts of the complete assembly during removal to replace bearings, communicating your specific component part needs to a new or used parts vendor can become confused without a knowledge of the component names and locations within the complete stub axle assembly. Due to the increased number of requests I have been receiving lately, I put together a composite photo image with labels to help my customers communicate with me. Maybe it will be of some help to others in the Datsun community as well.
