Default Help choose my next mod.

I sold my lincoln (old winterbeater) so I figured I could treat myself to something.

My cap is $300.

Options:

3.73's and an install kit- ~$280
MWC front bumper support- ~$150
MWC SFC's- ~$145
Founders SFC's- ~110
Founders LCA's & relocation brackets - ~$120

Suggestions?
I'm leaning towards gears, I'm currently running 2.73s.
Mods in sig.

3.73s for sure....
you say your cap is 300.00 so unless you are getting the set installed for free you will need a few hundred more....

Guy that rebuilt my trans is installing them. I'm not considering the installment price as part of it. If set up correctly, what's the chances of having issues with 373s?

Dont forget a tune adjustment for new gears! But I think 3.73s would be a HUGE difference, the biggest you will feel for $300.

Tune? Wouldnt the only thing I would need to change is speedo recalculating? It's a 93 so, 700r4 trans.

Shouldn't need a tune... But the recalculating is different on the 93's.. Different from the 94's and up.. Not sure what has to be done to recalculate but I would like to know too.

Install kit-

I'll need new axle bearings and fluid. I believe that's it.

Should I get synthetic fluid or get plain Jane 80-90 and a tube of gm additive?

They are a pain to get set up, but I have heard they are one of the keys to having a 7.5" last for awhile. I personally hate to see you spend any money building a stock rear, but your an automatic so it should hold up okay. If it were mine, I would look for a cheap (around $250) complete 3.42 rearend and run that while I saved up for an aftermarket rearend.

There isn't much on craigslist, I made a wtb post on the local board. We'll see if anything comes up.

I'd post one in the WTB section on here too. You'd be surprised how many people check that thing several times a day.

Shipping alone would be crazy high.

I found one locally. Problem is, I think he has a 4 channel with tcs. I have a 3 channel. Would it matter?

Yeah....your ABS light will be on all the time...and your ABS won't work. No easy way to adapt a 4 channel rear to a 3 channel car. Three channel rears are far more common though....so I bet you'll find one soon if you hold out. I'd bet you can find one within a couple days.

I'd get that after confirming it is a 3.42 if it's local and in the $250 range.
My reasons: 1. Cheaper than your planned gear change...savings on the parts plus no setup labor costs. 2. Should be quiet and dependable since it's OEM vs. replacements usually have some degree of gear whine. 3. You'll still have your old 2.73 to either sell, keep for a complete spare, or just sell the brake parts off of it and keep the rest for a spare. (Just selling the brakes should get about 1/3 of your money for the 3.42 back.)

The only downside is that you'll only get about 2/3 the gain you would going to a 3.73.....but that also means less of an economy hit too.

Your parts alone would be just over $300 shipped. Put the $50 savings plus whatever you get for your old rearend and you should have about $200-$250 (plus whatever you would have paid for the gear install) to save towards an aftermarket rearend later.

Thanks for the help. It's definately the better choice.

He wants $350 with a aluminum driveshaft.
