I check the reference forum.
I am a newbie here thanks for the help.
I have a 65 Impala that is a 350 with turbo 350.
I am converting to 4 speed manual.
I bought all the required parts from Hubbard for the conversion.
Here is where I have some issues...
1- The z bar tube is too small for the ball studs that were provided.
EDIT Update- they fit it was the paint that took up some tolerance.

2- The z bar doesn't line up with block ball stud area But does line up with Bell housing where it is NOt taped or threaded.
EDIT Update Drilled tapped bell housing

Is this common on a swap

I believe you may have received the wrong part(s). The Z-Bar pivots between a slotted tab welded to the frame and a ball stud screwed into the block.

first off make sure you have the correct bell housing for your swap. most small block factory set ups used a 10 1/2 in bell housing and was already tapped and threaded for the z bar ball stud as thats where it goes on our full sized chevys. frame side ball stud was machined to fit the slot in the frame mount and secured with a 3/8 x16 locknut. secondly the throw out fork is unique to these cars and isnt being repopped just yet, and is needed for correct linkage geometry so finding one is a task all its own.then will come finding the pedal assy which there are some still out there so not to tough to come by.

cfar,
If I remember correctly (and that is becoming a problem!) you can disassemble your existing pedal assembly and add a clutch pedal to it. You will also need to weld the support for the frame side of the Z bar in place, it's location is shown in the assembly manual. To weld mine in place I had to remove the left side inner fender panel.

I concur with vet65b that I think you don't have to replace the whole assembly, just the pedals. I swapped in a 4 speed in a 79 Trans Am and with that swap we just needed the pedals. As I recall, for an automatic, there is a pivot pin for the brake pedal that is removed, and the clutch petal has a pivot pin attached and goes in its place. The brake pedal then rotates on the pin that is attached to the clutch pedal. The brake pedal for a manual trans car is smaller, so it does have to be replaced. However, I believe that you don't have to replace the brackets that hold the pedals in place.

Thanks for all the help-I drilled and tapped the bell housing and all is good.

Can you post some images of the conversion? I'm planning to do the same on my 65 and anything will help. Thanks.

Sorry didn t take pics.was in a hurry to drive it-its pretty straight forward-just had to tap bell housing for ball stud...All the parts-pedals,linkage and hardware are available from many of the vendors.The trans,clutch flywheel and bellhousing I used was from a donor 66 chevelle

As mentioned above, you will find that the clutch fork that is in your Chevelle bellhousing won't work in your B body. Also, the ball in the bellhousing that the fork pivots on is not the same as B body.

I thought I would post the link to a thread where I did this conversion on a 1966 Canadian Pontiac. Before you guys comment that a Pontiac is not the same as a Chev, it is in Canada. The Canadian Pontiac 4 speed cars in 1966 use all the same components as an Impala, and the floor pan is Impala as well.

Hope this helps---
