For halyards, I just received some pre-fabs that I ordered from West Marine; turns out that they won’t crimp them for you at the local store (thank their lawyers), but they allowed me the use of their tools. It’s more work than you might expect! LOL… A larger person would just put his weight into it, but I was literally hanging off of the lever and bouncing my weight on it while my son supported the bench to keep the shelving from peeling off of the wall…
But I digress….
Per the parts catalog (under historical docs in the library here), original specs on the main were 27’ of 3/32 wire and 34’ of 5/16” line; West sells pre-fabs using 5/16” line with 30 feet of each, so that works for the jib, at 24’ of cable and 31’ of line (I left the cable at 25’, but will trim if need be).
For the main, I went up a size to the 3/8” (6/16”) which is sold at 40’ and 40’. Reasonably sure it will squeeze through the sheave up top. Expensive screw-up if it won’t.
NOTE: the ones I bought are also made with 1/8” cable, which is 1/3 more weight up there. Excess. Hoping there’s no appreciable downside, but it was all they had listed.
You can go higher tech on the line and just go for total length; I would definitely look into the UV tolerance of the core before I had anyone strip the sheathing and for non-racer use, I don’t see a compelling reason to not leave it be. One Man’s Opinion; take it for what it’s worth to you.
On this page, there’s a chart comparing the stretch of the various lines (substantial scrolling involved).

I would be more concerned about that additional 1%-1.3% of stretch if I were running 30-odd feet of it under load, but with the cable on there I figure the stretch might add up to about an inch, worst case.
And the parts catalog confirms 60’ as the length of the mainsheet. Also specs 5/16” braid, which sounds pretty brutal on the hands, so you may wish to improvise a bit.
Hoping some Old Hands will chime in.
