Wheel Adapter Help !!

Found a set of wheel adapters on ebay ... 1.25 thick ... nice pieces...

QUESTION ... They did not have a 5 x 4 to 5 x 4.5 .....but they do have a 5 x 100m to 5 x 4.5 ..... 100mm is 3.94 inches ... will this work with the 5 x 4 bolt pattern...? Is it close enough, or will that 6/100 make a difference. if so, can they be relieved by drilling?
Trans Dapt part# 7066 adapts 5 on 4 to 5 on 4.5.
It is 1" thick and as with all adapters, you must periodically re-check tightness. I ran these for about a year on my Duster until I installed my disc brakes and 8 1/4 rear axle. I had no trouble, but did not subject them to high speed cornering. A temporary solution at best, I passed them on to my brother, who now has them on his /6 dart.
