Default What is this Part on 1966 Corvette

I am going through the suspension and steering on my 1966 Coup. I am replacing parts to original OEM, Can anyone tell me what the part is / part number for the strut just in front of the oil pan?

"Shock Absorber Asm" p/n 3178100, as shown in your AIM at UPC-9, Sheet A3. Service operations are covered in ST72 Chassis Service Manual, Steering Linkage section, pgs 9-31, 9-33. Originals are Delco/Pliacell products with date code & p/n stampings on the tube near the bracket end. GM P&A catalogs call it a "... strg. shock ...". Aftermarket (repro) are pricey & normally referred to as a 'steering damper shock'.

It is not required for driving your car. But you can probably find a new service replacement if you search around . Original can also be rebuilt for $$$$......one or two folks do this work.

Dan, was that a direct fit for a C2? It don't show fitment on Summit's page, and shows up as a ford replacement on another site.

the only thing that will not be a direct fit is the stud on one end. I was able to remove the one from the original shock and weld it to the new one.. if you don't want to go to this trouble, a bolt should work just fine. the replacement part has open eyes on both ends.

Mike,
Keen has them on back order. Might want to give them a call to see what the time frame is for availability.

FWIW: I dug this old photo out of my files.(Not My Car) If your C2 has sidepipes and manual steering it
shows how close the shock comes to the exhaust pipes. It will damage the shock in due time. I use
a exhaust "wrap" bought through Summit to protect the shock. The "wrap" can be taken off when car
goes through judging then put back on. Thanks-Larry
