I'm about to swap some rims and tires with a guy.
I have a 90 K5 with 16x8 Pacer rims with 305/70R16 on them,
He has an 87 Toyota Pickup with 15x10 M/T Classic 2 with 35/12.5R15 on them.
I'm looking to go bigger and he's looking to downsize.
I looked them up on a chart from 4wheelcustom.com and everything matches up except the lug nut sizes:
90 Blazer shows: 7/16
87 Toyota shows: 12x1.50
Will this matter??????
I just want to make sure they will fit before we try.

Thanks
