Davis DA-2B nose gear

The Davis that I am part ownership of has a spring on the nose gear tube, and we have noticed that the top of the tube is hitting the alternator when it is completely compressed. The plans call for shock pads that are used on an ercoupe main gear. The problem is, a company that sells the pads told me that in I.D is 1" and our tube is 1.5" O.D. Are these shock pads modified or there some other shock pads that are used? If anyone has any info, that would be great.


Maybe this is way off base for what you need but I just did a quick search and found these:

Not sure of the rubber composition, but a quick email or call could get you the info you need. Clearly there are options out there. And if it was certified part it would cost $75.00...

I would suggest looking at McMaster Carr. They have rubber rods with 1 1/2 inch ID, 3 in OD. You can buy it is 6 in lengths, or 36 in lengths.  They have several durometers (Shore A)

They can be cut to any length, and stack them, or to the one piece the size you with. Below is the information for the tubes.
