TI Flatwound - A String - minimum length for Fender P or J model?

Hi - I'm a Rickenbacker 4003 player and bought a new set of JF344 Thomastek-Infeld Flatwounds. The Ric has a 2 x 2 headstock and I accidentally cut the A string too short! Yeah, I know - you'd think that after 50 yrs as a bass player - lol. Anyway, the A string is brand new but cut to a length of 42 in. I'm wondering if this is long enough for a Fender P or J player to get at least one or two full windings on the tuning post for an install that won't slip. Can anyone please verify this? These TI Flats are amazing sounding, but expensive - I ordered a replacement for $20 for just the A string. I'm thinking I could pass this new string on to a Fender player as long as I can be sure there's enough length for a secure install. Thanks!

Actual string info - JF34070 - Thomastek Infeld - .070 - new condition - cut to 42 inches.

 

Thanks - this is exactly the info I was after. All the best.

 

I have to agree - it's been awhile since I owned my P-bass, but I feel that 3 inches past the center post of the tuner is plenty to secure a string on any bass.
