John is a good guy, and definately knows his stuff.

Another option, if your interested.....

I can supply you with a kit to convert your current struts to height adjustables. The kit includes; threaded tube (advise diameter of struts), lower spring seats, upper spring seats, and adjusting spanner. This kit is designed for smaller diameter springs - springs are not included, but are also available. Cost is $345 (inc GST) Each kit will do both front struts.

Fitting is also available upon request.

Pic of kit fitted to struts can be seen here:

Note: Adjustable strut tops (pictured) not included.

Mark.
