I have thought about it. I'm just concerned about how it would work with the water pump and accessory spacing.

I hear you. I have a standard thickness plate with a corvette water pump and fbody balancer. Seems to line up close enough but may have to end up using an electric pump

I bought a Corvette water pump and balancer to get all the room I could in front of the engine. I also bought a Dirty Dingo alt mount set for the Corvette spacing.

Iíd say so.
Was that before the video of him tagging the wall at the strip? The quarter didnít look bad besides where he opened up the wheel well.

No. that was before it got tubbed. You can see all the body filler in that quarter.

Finished up the motor and trans mounts this morning. Plated the top of the floor to help support the new trans crossmember.

Good idea on keeping the mounts as far forward as possible. Much better than what I started with.

Finished up the gussets on the motor mounts and finished trimming what needed to be trimmed in the trans tunnel. Everything up front clears. The crossmember, rack and even the sway bar.

What do I need for a u joint that will fit the Chevette rack? I assume I will need to cut the Chevette steering shaft and weld a piece of double d shaft in it?? I've never had to make a steering shaft before.

I don’t know the joint but as for welding in the shaft that’s all I did. Couple plug welds up top and all around the bottom. I took my time to not overheat the shaft it felt like it had a hardness tonit I didn’t want to mess with

I found out that the Chevette rack is a 5/8 36 spline. Do I need a 3/4" DD shaft to weld to the Chevette column?

Iím pretty sure thatís what I went with. Hereís a picture I had on my phone. I think I remember sliding it in and having to flatten both sides.

Well no luck finding my spare u-joint to measure. Can’t get a tape or caliper down properly to the shaft on my car. But it’s definitely a double D shaft.

Starting to get my firewall made. I got the left and right sides ruffed in. I just want to get everything fit around the trans before I pull the motor and weld it up.
I keep looking at Corvette exhaust manifolds. I think the side profile of them wouldnít be an issue but I think they will be to wide.

I needed some actual Chevette parts so I picked up another parts car. I wish I could get Camaro's this cheap everyday. This things a peach. Scabbed together floor and there's expanding foam between the hood skin and braces. Runs like a champ though and it's even got power steering. First time I've seen one with power steering.

Starting to make some progress on my firewall. Hope to have the trans tunnel tacked together tomorrow night.

Made some more progress on the trans tunnel tonight. Hope to have it finished up tomorrow. Atleast tacked up anyways. Then I need to figure out where and how I want to mount my pedals.

I got the passengers side of the trans tunnel finished this morning. I decided to widen the tunnel past the end of the trans because u joint clearance is limited. Iím happy with the way itís turning out.
