Where to buy original dip stick tube?

[Oliver S.]

Hello,

I'd like to buy an original (looking) dip stick tube for my '65 300 hp engine. Corvette America sells a chrome one, but I'm not sure if this is original. What supplier(s) offer(s) a correct dip stick tube? Is it perhaps availble from GM? Thanks in advance.

Regards
Oliver

The tube is still available from GM. It's GM #3865664. This is a non-chromed tube; the original tube for your engine was not chromed.

The above-referenced tube is not, however, exactly like the original used for your application. The difference is the upper portion of the tube. The original tube had a swaged-down section near the top. In this configuration, the upper OD of the tube was a little smaller than the lower OD or the main section of the tube. Paragon manufactures a reproduction of the original style tube if this facet of originality is important to you.

The GM replacement tube will function perfectly.
