Starter Bolt and Oversized 240Z 260Z 280Z 280ZX 510 620

Starter bolt for all "L" series engines.  We have found that the original starter bolts can be a little short if adding a ground cable to the bolt or in some cases we have found starters with thicker flanges than stock, in which case the stock bolt has trouble catching the threads.  Here are 2 options for longer than stock bolts: 

A:  3mm longer than stock, works as a stock replacement or if adding a ground cable.

B:  9mm longer than stock, works with thicker flanged starters
