WTB - 86 Sprint QV Strut inserts

Hi all - I am after some strut inserts... or new struts (if u have some in your back pocket) for our 86 model Sprint. I believe there is a possibility of interchange with a 33... also any info about the interchange would be great.

if you use 33 struts do discs, calipers etc alter?

Happy to pay transport

Thanks
Mark
