2 Cap Questions

Question 1:
I recently restored an RCA 14PD from the late 50s that used vertical paper and molded caps mounted on a circuit board. Both leads are out the bottom. I ended up using axial polys and running one lead down the side. Great for servicing (you can attach test leads from on top on board), but doesn't look very original. Is there a source for replacement vertical mounts? If not, are there some other ways to tackle this?

Question 2:
The audio output transformer section of a tube radio (German early 60s) has some 1000v molded paper caps. The B+ supply to the plate of the output tubes is 275v. Do I really need 1000v caps and if so, where do I find them besides as ceramics?
