1990 Chevrolet Silverado 1500 Step side
Run's great 350 Chevy engineAutomaticA/C Clutch comes on but needs charged
New parts in last 2000 milesRadiatorAlternatorBatteryFront and rear GlassNew front pads rotors and one caliper
It does leak oil from ? and a tiny bit of tranny fluid from rear seal because it's missing a 2'' lift block of the passenger rear making the driveshaft sit back too far.
It's my daily driver I bought it about 4 years ago drove it everywhere sold it to a friend bought it back last febuaruy and it's been my daily driver since and never let me down unless I ran out of gas and the gas gauge does work so E means E don't chance it lol.
It does need a little work but like a said runs and drives so here is what i know she needs.The steering column is a little loose needs a bearing or replaced It has been like this for 5 years I just drive it.a drivers front shock there isn't oneI only have one key to the ignition and no door keys they are $10 for a new lock set.the exhaust probably needs replaced or repaired and rear brake cyl on right tear tire leaks.She puts out a puff of smoke at start up due to worn valve seals
NO knocks run's strong she'll lay a nice patch until you let off the throttle
She's made me a good amount of money but have a newer bigger truck so needs a new home
Thanks for looking.
