sleeve-valve Posted November 9, 2011 Share Posted November 9, 2011 My parts book lists them as 2103A and 2103B. Other places like Apple Hydraulics website lists them as 2103E and 2103F. An older post says the E and F are replacement Delco numbers. What is the difference between the A/B and E/F? Is one pair considered better to use than the other? Thanks.

Guest Grant Magrath Posted November 9, 2011 Share Posted November 9, 2011 Do you have them? Or are you looking for some? CheersGrant Link to comment Share on other sites More sharing options...
sleeve-valve Posted November 9, 2011 Author Share Posted November 9, 2011 Do you have them? Or are you looking for some? CheersGrant I have one marked 2103F on the left rear of the car that seems to work fine and doesnt leak, the one on the right rear leaks and is unmarked so I don't know what it is. I have a used 2103A and 2103B that are not on the car and I dont know how good they are, so I'm thinking I can either rebuild A and B or look for a E and rebuild it. If I knew one pair was better I'd go that route, otherwise I'll just rebuild A/B and have an original matched pair. Link to comment Share on other sites More sharing options...

Didn't say a lot for our roads back then!CheersGrant Link to comment Share on other sites More sharing options...

For some unknown reason our government only spends 5-7 cents in the dollar of taxes collected in the name of "road taxes and levees". Having done a lot of miles in a '39 here in Aus I can attest that those big series shockies do smooth out those ruts and bumps.Danny Link to comment Share on other sites More sharing options...
airbrushguy Posted November 10, 2011 Share Posted November 10, 2011 I have a full set of used 39 shocks if interested. Link to comment Share on other sites More sharing options...
