raising rear ride height

I have some H&R springs on MSM Blitstiens on my 96. Rear ride height is too low, maybe 3/4 inch lower at the pinch weld than the front is. What's best/simplest/cheapest option for raising the rears 3/4 to 1"? Some kind of spacer on the perch seems the most obvious to me, but maybe someone has experience with this issue on NA/NB suspension?

Also, it has NB rear tophats, so maybe just NA tophats??
TIA

Bigger wheels/tires! ;)

NA tophats will buy you around 3/4".

PS
I have a set of 4 if you're interested.

Got a pair of NA hats, will see how they do.

The NA tophats seem to have done the trick. Thanks for the info!

Seems to ride a bit better now too (relatively), I think the shock was near full droop with the NB tophats on the already-short springs.
