Steve & Eduourd , thanks for your experienced advice. My 430 is stock and won't be wild for many years to come after I get my career going, so the boxed frame I guess won't be necessary. Thanks for the rear end tip, another confirmation i should be running a 3. series rear gear, was once told not to go above 3.55.
The vinyl looked so good I thought it was leather. I do have a small rip in one of my seats, can you guys recommend a solution?
I will look into 303, thank you for the link.
Why do you think that my th400 has Chevy mounts, it was from a 73 455 Pontiac car?
Another thing I forgot to tell everyone is that I had purchased a HD th400 out of a RV just for the strait cut gears, they are stronger but noisier, I got the trans for 25$ so I hopped on it. Most likely I'll be running those gears because I'll be pounding on the Skylark
