Been trying to locate information on the proper Throttle return spring setup for a 68 Firebird 400 Ho ! Can someone give some feedback on what determined what color was used ? Example Blue or Yellow and did it use two springs to return the throttle ? or one ? .I attempted a forum search to locate information on about the springs but was unsuccessful. Also were the Original retaining bolt's ( for the oil filter adapter to block) a hex headed bolt ? or did they use the 12 point headed bolts like the fuel pump used ? Trying to put back together a 68 HO Coupe I purchased as a basket case Thanks in advance

Thank's Scott for the response , Do you know if the throttle use one or two spring's in conjunction ? I know I've seen the blue one's over the year's and can not remember if it use two springs ! Also are you saying the oil filter adapter is bolted to the block by hex headed bolt's ? and then is the oil filer housing bolted to the adapter block with hex head bolt 's ? I was wondering because when I got this car the motor was completely disassembled but the fellow had the filter housing loosely screwed to the adapter with two bolt's that appear the same as the correct fuel pump mounting bolt's ( the 12 point headed) bolt's ! Thanks again for your time
