FTDNA has a bigger database, listing a large number of distinct 12-marker
haplotypes where the haplogroup has been proven with a SNP test. If their R1b
"best guess" was a close one (say zero or one mismatch), the odds are good that
your father is R1b, but of course, only a SNP test can prove that. After all,
R1a and R1b do have a common ancestor, and we would expect them to have some
similarities.

The second set of markers may not be of much help, since FTDNA's "best guess"
is based on the first 12 markers only. You'll need to compare your markers
with other people who have had a SNP test.
