That seem to be working, i pasted it into the standard.jft and it popped up in the "pick a new jfet" list. Thx

Now im just gonna add the MJE340/350 and the MJL4281A/4302A and i'll be done.

MJL4281A/MJL4302A is probably almost the same as MJL3281A/MJL1302A
I use andy_c spice models
andy_c has done good models for MJL3281A/MJL1302A
