Is the same bolt pattern utilized from a 95 K 1500 4 wheel drive and a 95 Tahoe the same bolt pattern 6 lug

Bought a set of 20 inch rims for my Chevy 95 K
1500 4 X4 supposed to come off a 1500 6 bolt
pattern is that the same 6 bolt pattern cuz I cannot
get them to fit the guy I bought them from change
the story to they came off a 95 Tahoe which in 95
you can only get 6 bolt lug pattern and four-wheel
drive so they should not right on my truck but they
don't is there an adapter I can buy to go from the
six lug K 1500 to the 6 lug Tahoe which is a 95 2 or
a spacer or adapter to go from a 6 bolt 95 bolt
pattern to maybe a 2002 I'm thinking bolt pattern
the problem I'm having is when I mounted them on
my 95 K 1500 the bolt pattern on the rim is slightly
bigger than the bolt pattern on my truck thought I
could use a unibit to widen out the lug holes but as
I found out there won't be enough room on the
sides to put the lug nuts on please I need help
spent too much on these rims to throw them away
