So I'm upgrading the fuse block in my 1966 chevelle. I ordered the universal fuse block from Painless wiring to do the job. However, upon attempting to remove my old fuse block, I'm having trouble gettin the old one out. Any tips for removing the old block and has anyone installed one of these Painless fuse blocks before? Any suggestions are greatly appreciated!

If I recall correctly, there are two sheet metal screws holding the fuse box in. On the engine side, there is a screw holding the wire harness to the fuse box. If you've got them out, I bet it's stuck on some sealant and needs a little tugging.

Correct on the two screws inside, but I don`t think there is one on the engine side of the fuse block on a 64-67. Unless you are good at wiring, the Painless may not be the way to go. I`m not saying you can`t do it, just that its not "Painless". American Auto Wire now has the upgrade fuse block for 66-67 chevelles. Real nice set up, but require more labor to install as you have to install all the ends on the wire and build the harness, but it is labeled.

I agree with Tommy.
I replaced the original fuse box in my '66 wagon with the AAW one.
Good stuff.
The Painless one is more generic...the AAW one is plug & play and complete with the correct wire color/gauge and ends.

I say this about "Painless Wiring". If it's not an oxymoron, it's darn close in my opinion. Not to be confused with "Painless Dentistry"

M&H is a great product also.....original PLUG AND PLAY. I suggest looking up MADElectrical.com for some enlightenment about some things you might want to do....i.e. relays for headlights, separate electric fan/headlights and main fuse box, shorten main fuse box power lead, re-route alternator to battery charging wire to be shorter. Lots of good information, including the 1 wire vs. 3 wire alternator. Do some serious research before deciding on exactly what you want.
