4.3L v6 to 383 sbc motor mount problem

I am swapping my 4.3l out of my truck and putting a steel sbc 383 that i had built. Ive been told by several people the motor mounts are the same but after pulling the v6 and measuring everything out when the 383 sits in there the block mount is about 4" too far forward.
is there an adapter kit for this?
i cant really put a weld in kit because on the driver side the steering is right in the way

thanks
brad

The truck should have different sets of holes for different motors .
At least the full size chev do .
There is a pile of S-10s with small blocks in them too
Some people use the pre 71 mounts on the S-10s
I put a V-8 in a 81 full size where a straight six was and had to move the mounts into the proper holes ..
Same mounts ; but had to move them

the trucks a 2006 chevy silverado 1500, theres no holes to change to but I actually ended up finding a adapter kit after awhile of searching. can use the stock mount locations and stock rubber mounts.

if anyone else is looking for the same thing here is the link

Hey Brad, Richie here! Are you sure that mount kit will work? It says its for S10, I thought you had full size Silverado.
