ok just got my 1978 camino yesterday abd it has an 86 front end on it the first thing im doing is pulling off both doors to repair hinges,now which leads to my question..it has the typical roller thats worn out and wanted to know if gm or after makt has come up with a better design or replacements for them? i got a used set but they arent in much better shape than the old and just for clarification its not the pins thats causing the sag its the rollers,so have there been any improvements or tricks since 1978? which is the last time ive owned a gm product sorry to say lol, i just dont want to put on these hinges and have to go thru this again for awhile if possible. thnx in advance for any and all assistance. bb
