Sig .380 information request

[NikA]

Not a Ruger question, but hoping someone here can help me out.

I acquired some Sig P290 .380 parts but lack a recoil spring.

Looking for the following dimensions:
P290 .380 recoil spring uncompressed length
P290 .380 recoil spring force rating
P238 recoil spring guide rod length
P238 flat wire recoil spring uncompressed length

Thanks in advance for your help!
