Sorry dumb question

[slyguy_22]

Are the lug patterns on the older 69-72 blazers 6 on 5.5?

 

[bp71k5]

Yep.

 

[slyguy_22]

thanks so then the new caddy ext wheels should fit also? 6 on 139.7 ?

 

[bp71k5]

Not sure about that, I only know the lug pattern is what you gave.

If my math is right, 5.5 inches equals 139.7mm. 1in = 25.4mm.
