Hi All. I am trying to remove the instrument cluster on my 1973 450SE (W116.032 M117.983). I have read some older posts that explain quite clearly that I remove the molding under the steering wheel, get my hand up under the dash and push the cluster out from behind. I tried this last night, but the cluster feels really solid - it wouldn't budge at all. How hard do I push? Anything else I should be doing?

Thanks in advance,
Joe
