frustrating led bulb 74

[vmchurch]

So a while back I went about ordering a bunch of LED 194's and 74's from superbrightleds.com for the gauges....problem is the 74's didn't fit into the OEM sockets, the base is about 1mm too wide

Question for those who know: What size base 74 will fit?? THey sell them in 3mm, 4mm, and 5mm.....Help
