3.5" dash speakers...my options?

[pcmcobra]

So I have my new radio in, and all the power/speaker wires run. I want to replace the dash speakers.
Will 4" fit without any cutting?
If you have 3.5" or 4" replacements, could you please reply with brand and model#?
I have been looking at several different brands, but some brands I can not get exact specs on how high the tweeter protrudes. So If you have replacements, please, let me know what fits.
thx

my 85 had the factory 1 speaker in the middle of the dash. i just installed 2 new speakers last weekend. if you have the brackets that are used for the 3.5 speakers-you can take 1 of those to help with speaker size selection.i found some pioneer 4 inch speakers that worked fine without hindering installation of the dash. all i had to do was trim off some of the screw tabs on the speakers and drill new speaker mounting holes in the brackets.i used small metal screws/washers to install the speakers onto the brackets.if you dont have the brackets-look in junkyards or   catalog.hope this helps.
