Suspension upgrade Qs for '65 coupe

[stanger66]

best thing to get the welds off are power drill w/cutting off tool attachment with a steady hand.
With the suspension kit I would take a look at www.mustangdepot.com 's suspension kit, I think it comes with more choices and is pretty reasonably priced. If youre getting new leaf springs go with 4 or 4 1/2 leaf. They will probably be right around what youre looking for. I'm putting 5 leaf race springs in my 66.

Got the export brace and monte carlo bar on with much pushing and pulling, and at the cost of a very sore back. Sometimes it just doesn't pay to be tall, heh heh...

I picked up an angle grinder from sears with some cutting and grinding disks and went to work on the old 4-piece. Fun times. If the old export brace wasn't metal, I would have loved to ritualistically burn it before tossing it in the garbage.

So the 5 leafs that come with mustang plus' "street heat" kit would be a bit much for a moderately modified (eventually) car? How about the 620 springs? They say that the 5 leaf mid-eyes and 620s drop the car an inch at all 4 corners. I'd like that, I'll check and see if I can get the same ride height with the 4.5 leafs. Would I still go for the 620 springs if I choose the 4.5 leaf springs or should I go with something less stiff? Also, if I go with poly bushings, is that going to rattle my car around like those ricers you sometimes see that seem to have no suspension travel at all? I'd honestly rather have rubber that I'd have to change more often than a ride THAT jarring.

I appreciate the answers, everyone. I'm thinking I'm gonna wait a month or two before buying a kit in order to give myself time to research this stuff. I want to make sure I get this done right before I spend a nice chunk of $$$.
