Now it's time to post some photos to cheer You up after cutting such a nice car :)
First we put the body on the floor to see what fits and what doesn't.
Rear looks rather good, front was left with too much metal in order to clearly see what had to be cut. Measuring of course continues...
After making necessary cuts. Looks good. In front it would be difficult to join everything, as there are a lot of things to care about. The firewall happened to be about 4" forward than original one, so is front seat. That was not expected, so i was worried if the front seat would not be too forward. After measuring and comparing to previous position we agreed that it would be ok. On the other hand rear legroom has been greatly improved :)
Passenger area fits very well, everything aligns good.
That's how it looks.
Rear inner fenders in Buick were closer to each other than in Caprice, but it also aligned well. Question is should we leave the trunk floor as it is, or lower it (along with rear part of the frame) as it was in Buick originally.
Rear part of the floor in Chevrolet had also lower part for trunk passengers legroom, it needs to be modified to meet Buick's rear panel in original connection point.
Initial welding of two firewalls together.
If measuring will assure me it fits, it is a chance to use Chevrolet's air conditioning.
Rear seat will go here. Fits real good.
Drivers seat position. I think it will be ok :)
