What truck came with 454 & SM465 manual tranny

[Burt4x4]

Hey Gang
I just put a 454 in my 72 K5 using my stock SM465 and bell housing.

I need the shields that bolt under the bellhousing and starter. I had to 'open up' the crank area on my old shield that the 350/SM465 used. I would like the get the right shields instead of running modified SBC shields.
I hope this makes sence???

So if I could get an exsact model chevy that came with the 454/sm465 combo in 72, I may beable to get a stealership to find a new set of shields???

all comments welcome
Thanks for your time
Burt
