I found this.... Will it fit the 81 blazer? I'm going to admit something embarassing too...... I don't know if it's 1/2 ton or 3/4 ton..... are all blazers 1/2 ton?
1982 Chevy Half Ton 4 X 4 Power Steering Gear box
Up for auction is this power steering gear box that was original equipment on a 1982 Chevy half ton 4 x 4. When it began to leak, I replaced it with a re-man and sent this one in to get re-sealed, (to the tune of about $165.00). The re-man that was installed had far more play and did not have quite as tight of a turning radius as this one. Unit comes with mounting bolts, spacers, and steering column connector.
The numbers stamped on to or cast into this unit are:
On the top (as if it were mounted) 7802644 L and 197 and 09
On the bottom (as if it were mounted) 4 L
I was very happy with this unit, but traded off the truck before getting it re-installed. I no longer need this gear box. I think a starting bid of $50 is a GREAT deal for you, the buyer!!!
Feel free to email any questions. I’ll be happy to answer, if I can.
Winning bidder will pay actual shipping charges. I will not charge for packaging the item.
Thanks for looking and GOOD LUCK!!!
