After doing lots of research trying to figure out how I'm going to run my built c5 t56 & diff in my 05 I see people making brackets for the c6 cradle to accept the c5 rear diff mount. My question is I have a c5 cradle, is it a direct bolt in without having to modify or fab anything else?

Good question. I know the C5 guys put C6 cradles in their C5's when they swap to T6060's and Z06 diffs. They also require the upper a-arms I believe. Other than that I would think it would be a direct swap.

Are you that opposed to using an adapter bracket though? Seems pretty drastic.

Edit: Just read that you already have a C5 cradle. So I think you're set along with upper a arms.

So your saying I would also need to use my c5's upper control arms as well?

I called rpm transmissons and was told I could use the cradle but it will push my rear tires forward a Tad.

I may just look into building a bracket for the c6 cradle. I'm just not a fabricated so if duck tap or zip ties can't fix it then I'm gonna have to pay someone to weld me up something which could cost more than what It's worth.

It's either the uppers or lowers, can't remember. I've never actually done it, just going off of what I've seen the C5 guys do.

Now that you say it I remember the C5 guys talking about their tires being pushed back a bit so that makes sense.

I'm using Stanger383's bracket, just put it in. I have a vibration but I think it's because I didn't shave down the cooling fins on the bottom of the diff enough and it's sitting on the leaf spring.

i have seen some very good detailed write up s on this with great pics. actually pretty easy swap and the fab for the bracket isnt bad.

There shouldn't need to be any fab if the cradle is swapped.

Is it a constant vibration or only under certain conditions? I didn't shave any off mine. No noises or complaints at all. Never hear or feel anything while driving. I just have a slight vibration for a few hundred RPMs around 2500 or so...

It's from ~2500-4000 and it's at its worst at ~3000. It'll do it when I'm sitting still in neutral but its worse when in gear. I checked my fins and nothings touching.

brodyscorvette

Mine didn't appear to be touching either, so in my quest for laziness I didn't shave any.

Guess I should do that some time tho.

Thanks...

Are you guys making your own brackets to fit the c5 diff on the c6 cradle?
