I have 1988 Chev CK1500 W/5 speed Won't go into Reverse

This will FIX that Getrag Shifter was FLOPPY and won,t go into Reverse. Remove shifter on top of trans, there is a Roll pin in socket inside the trans on the shift rail or rod it will look ok But NO Tap that Roll pin out and use a magnet to pick it up and tap in new Roll Pin P/N 8672316 32mm long. From E-Bay .See google see Transmission HM290/5LM60 and see pin at bottom cup for shifter . BABY this WILL fix that Getrag!!!!
