thx you guys..I appreciate the input..and I think i fixed it...
Ok here is what happened..the previous owner installed larger diamter lug studs on all 4 wheels....they were not however 1/2 20's like i though..they were some kind of metric size...well i didnt want the metrics on there so i got some 1/2 diam studs for a 72 chevy and they worked fine for the fronts...perfect...but the rears are a diff story....
The p/o obviously drilled out the front hubs and rear axles so that the bigger size knurl would fit with the new metric stud....well he drilled it bigger so i cant use the origianl 7/16......
the 1/2 fit perfect on front..but not the rear....the knurl(shank ??) is way too long and the wheel wouldnt bolt up cuz the lug nut wouldnt bottom...so i got a dorman catalog and looked thru it and found the same size knurl as the fronts (so they'd fit corect in the hole) and the right size shank length so it wouldnt interfere with wheel seating properly......i get the studs i ordered tomorrow so ill see if they will work for rear...
this is a royal pain in the you know what...I really wish the p/o would have left it alone stock 7/16.....would have made my life much easier.....this is the 4th or 5th day of me messing with it...I got my rallys a week ago and was so anxious to install them...been quite an experience....but it all goes well i'll have all the rallys mountd up with matching 1/2 x20 studs and takin a cruise b4 xmas day!
