A google search for “fritzing part bridge rectifier” (since I remember fixing one up 
) turns up:
and there may be more I think, perhaps one more suited to what you need. Again if you have a data sheet for the one you have I can make a new part for it.
Best bet is to measure the spacing between the leads. If it is a multiple of 0.1in (and less than 0.3in) you can change the package in inspector to get a bigger cap. If they are larger than that then you would need a custom part made for them and we would need the data sheet or measurements of the cap to make one (assuming you want to mount it on the pcb!)
edit: forgot to include this image!
Yes. I meant to include my .fzz file (which has my new part in the temp parts bin where you can export it by right clicking on it and selecting export file.) Here is my .fzz
