Disco-Ron Posted August 28, 2014 Share Posted August 28, 2014 I have a 90 with a six bolt box, which has just sprung a fairly substantial leak... i have a 4 bolt sat on the garage floor waiting, can someone confirm that it's literally a straight swap.... ie, same threads on the input output pipes etc...... i don;t want to get half way through the job and get scuppered............ Thanks. Quote Link to comment Share on other sites More sharing options...
western Posted August 29, 2014 Share Posted August 29, 2014 6 to 4 bolt is a straight swap, pipes are same fittings, you will need O ring seals IIRC, use the 4 bolt box drop arm too, Quote Link to comment Share on other sites More sharing options...
Disco-Ron Posted August 29, 2014 Author Share Posted August 29, 2014 Many thanks. .... already ordered sumo bars and damper bracket in readiness. ..... Quote Link to comment Share on other sites More sharing options...
reb78 Posted August 29, 2014 Share Posted August 29, 2014 Yep. I also did this last year (maybe the one before). Literally unbolt the old one and fit the new one. All the pipes etc are in the same place. Quote Link to comment Share on other sites More sharing options...
mickeyw Posted August 30, 2014 Share Posted August 30, 2014 I've just done this conversion. The threads on the two steel pipes are the same. Quote Link to comment Share on other sites More sharing options...

sighnbox Posted September 3, 2014 Share Posted September 3, 2014 Just out interest is there any benefit from changing to a 4 bolt from a 6 bolt ....... Quote Link to comment Share on other sites More sharing options...
mickeyw Posted September 3, 2014 Share Posted September 3, 2014 Just out interest is there any benefit from changing to a 4 bolt from a 6 bolt ....... Not if it is working OK I wouldn't have thought. My only reason for changing was the greater availability of second hand 4-bolt units. Quote Link to comment Share on other sites More sharing options...
western Posted September 3, 2014 Share Posted September 3, 2014 IIRC 6 bolt boxes are not repairable, no one refurbishes Quote Link to comment Share on other sites More sharing options...
