I ran ISC coilovers in mine and it wasn't too low... In saying that It wasn't high eather.. Why not use aftermarket coil and then run a spacer on top of the strut to gain the extra hight...I used to have some 50mm ones here. but threw them out last clean up... made them with holes all the way rounf so you could rotate the strut top any way you liked.. more camber or more caster, or more of both. or more of one that the other.. ect..
I made mine from some left over billet round I had sitting around.. you could easily do it with some steal plate and some correctly sized tubing..
