[T3] bushing for front control arm

[Shari Hawkins]

I'm getting ready to get my '68 Notchback out again for the season, and I have a novice question for the group. Last autumn a mechanic told me I needed a "right front control arm bushing." When he had the car up, he grabbed the tire and showed me how he could jiggle the wheel. I had a really hard time finding a bushing, and the one part I could find ended up being the wrong size. 

Two questions:  
1)  Where can I find this part (if this is really even what I need)?
2)  Is it okay to drive short distances until I replace the part?

Thanks in advance,
Shari and "Cloudy"
