[Merv and Sharon]

Thanks Dennis. I am also looking at the Summit stuff. I looked at both the existing springs 2" and the 2.5" King springs and QA1 springs yesterday and in actual diameter there seems to be only 3.5 mm difference for some reason. When that is split each side they should fit through my rear upper arms. The QA1 501s are 17" extended, which is longer than my AVOs at 16".

However, in the mean time I will check out the QA1 fronts - the DD403s (which have a 15" extended length rather than the DD401 that only has 14"). The matching QA1 springs are 10" at the front I believe. However, there are heaps of varying springs lengths available. I think I will stay with my relatively 'soft' set up of 300 F and 250 R.

I will have no problems, I believe, at the front on the Harrison with spring diameter. Thanks for the advice re the helper springs - will check that out too.
