Hubcap 1961/1980s split rim to solid conversion

[Dazzoman]

This worked perfect , will for you too ! Smooth ride with the 1982 rims yet keep your caps !
Getting out of the 1961 split (8 lug ) rims is essential because they ride bumpy no matter how much you balance them . These are 1982 Chevy rims in my case. It was easier to have tires off so I could poke my eyes and hands to measure how far the springs needed to almost touch to inner edge of rim . I used self tapping screws but don't depend on those or you'll break them off . The rims are way tough/ thick so tap them properly with the right tool , grind off excess after Loctite applied . I got lucky on the thickness of the plastic spacers ,forgot the exact thickness .
1.Punch out rivets out of the old rims .
2. Right on the crease - punch , drill holes like on photo or enough to measure - I always started with two opposing each other until I got the recipe down that the cap would nicely pop on with just two .
Drilling is hard because material is very tough so be cautious , patient .
As shown cut , pre drill plastic spacers .
I thought I posted photos here ?
Will check to see if I can edit that ...
