Changing front Suspension Springs

[Benengo]

The near side front spring on my 1982 BMW 635csi has broken and popped over the housing. I've found replacement part at a reasonable price from eurocar part and am considering replacing it myself.

My question is how hard a job is it to replace? I'm reasonable with a set of spanners but not experienced. Any ideas on how long it would take? I'm guessing it is essential to do both at the same time?

also if i do get a pro to do it how many hrs labour should i expect to do both sides?

Many thanks!

Right don't mind getting my hands a bit dirty but would like to have the same number of fingers/hands/limbs at the end of it. The local garage has quoted 2hrs a side at £35/hr which isn't 1.1 hr per side but not extortionate so think I'll have a chat with them.

Thanks for your help... I love Pistonheads
