Flex-plate

Suncoast said that while a stock second gen plate will work in a first gen, their laminated second gen plate would not fit in a first gen.
I ended up with an "SFI-rated" PATC piece in my garage, they say it'll work but I'm waiting for an excuse to change it and find out for sure.

Do the above supply parts for first gens or are they second gen only pieces?

If you replace your stock flex plate with a thicker flex plate there is an easy way to use an after market unit.
The biggest problem you will have is that it moves your converter further back. Under heavy load the converter will expand enough forcing the input or rear part of the converter to make contact with your main seal on the pump.
This can also put more pressure on the pump causing it to destroy itself in some cases. You have a 50 50 chance it will do this. Really depends on how much power your truck makes.
The best way to correct this is to have the front hub on the converter machined down the difference so the converter moves forward the difference of the thickness of the flax plate.
It a simple thing to have done and you can run any flex plate you want after you have done this.

There are spacer shims available made of 1/8" metal that go between the bell-housing and the engine's adapter-plate.
For example: http://cgi.ebay.com/ebaymotors/48RE-...-/130372060572
I've a SFI rated flexplate like that Begle speaks of in front of a SunCoast converter. No clearance issues.
It's my understanding that with the trans bolted to the engine, and the converter NOT bolted to the flex-plate, one wants about an 1/8" space between the converter and plate.
This flex-plate will work well for most stock plus a little applications ~ http://www.puredieselpower.com/catal...ins-p-292.html

just trying to figure out what the best bang for your buck is. A couple hundred bucks is a lot for a piece of steel. Id rather put that towards a converter.

If you dont mind me asking, how do you like the suncoast? is there a noticeable difference?

It works well for me though I have had it tightened a little more than that they sell off the shelf. The goal there was to have it stall closer to the engine's torque peak.
You haven't said what you do with your truck. A work truck (for example) that needs a lot of torque multiplication to help get a load moving isn't necessarily going to benefit from a converter that's too tight. You'd do well to telephone your favorite vendor (SunCoast, Goerend Bros, Specrite, etc) and tell them what you're doing and they'll steer you toward that which would work best.
