Question on LHD Steering Arm Boot Material

Unknown

Evening all,

Doing some finishing cleanup after pulling the 29 Std Sedan engine last week. Please forgive on my improper naming. There was a wrap or boot around the steering arm joint to the drag link. Pretty sure its just to keep dirt out. 

What has the group been using as a replacement, attachment retainer, and should there be another on the drag link to steering gear level joint?

Thanks

Jack
