Make sure to measure the physical size, and also the pitch of the legs of the capacitors to make sure you get ones that fit!
Oh boy, simply ordering all these caps is a chore.. adding a verification of package size to the mix would make that chore exponent 3, and lead only to one thing : me taking a drive with my car and snedng it full speed into a big bridge pillar.
All these caps are for stuff from the '60S, 1972 at best (for the Tek 7603), so for stuff this old, I just take it for granted that the new caps are bound to be smaller than the old ones, and the lead spacing bound to be narrower, but it's not difficult to bent leads, is it. If for some strange reason the new caps were to be larger than the old one, strange but..... well, I would rather cope with the one in 50 caps that doesn't fit, special case it, rather than waste hours taking into account the package size each and every of dozens of caps. My time is precious to me....
However when I recapped the PSU for my Tek 2467B, I measured diameter and height of every cap because it's a more modern design and most caps had zero margin for error, either touching each other, or touching some other components of mechanical bit or what have you... so it was critical to look into that...
But I won't order them today... it's already 21H00 here and I am tired. So tomorrow maybe...
