Heathkit IG-5218 Re-cap question

Hello, Forum members.

I am re-capping my IG-5218. The P/S board is finished. I had purchased qty 2, 250 uF/50 V Sprague capacitors (axial leads) to replace the 250 uF/35V caps used for C6 and C8 on the Wave Generator circuit board. I think I would rather use radial leaded caps now. I am having some difficulty finding 250 uF radial leaded caps. Can anyone tell me what the acceptable uF range is that can be used for C6/C8 replacements or do I need to stay at the 250 uF value. Thanks in advance.
 
If I recall, those are oddball radial lead caps, so you'd have to remove them and measure the lead spacing.
Avoid buying "snap-in" capacitors, since those won't fit the holes because they have larger diameter leads,
and the spacing won't be correct anyway. Just get a part with standard wire radial leads.
