I have a spare driver's seat base so mocking up the install is painless.
The white studs are the factory pieces. The newer seat uses a much wider footing so I'll weld a 3/16" strap over the new base in line with the original holes and bolt it down. The mounts are much longer so I'll add 2 more bolts through the floor towards the back.
The passenger side factory bolts are much further back so I'll do the same welded strap overlay but add 2 new bolts through the floor towards the front.
