FWIW, originally the truck was a 454/auto (currently has a TH350, not sure if it's original or not) with an NP205 and a few HD suspension options - shocks and front springs, IIRC.

Re: Tranny / tcase problem
I ran without that bracket for over ten years beating the he!! out of my drive train with 36" Swampers. I did snap my adapter during a head on 55 mph accident though. When I went to replace it I spoke to a shop that rebuilds t-cases and that's it. They told me the one I had was a weak version. It had a support bearing. They said to get the one without that bearing as the casting was much stronger. I have two now just in case. I have that strut but cannot use it as I have a crawl box. If any one wants it for shipping costs it's free! I will recycle my t-case frame brackets...

Re: Tranny / tcase problem
This is an interesting topic, I am currently in the final steps of a 72 K20 build with car 427BBC/NV4500/6 bolt round pattern NP205. the powertrain is mounted to an 86 K30 motor and transmission crossmembers with 86 motor and trans mounts. I also installed the tcase to frame bracket. Should I remove the side T/C mount without adding anything else in place? Is this not to much cantilever weight for the NV4500 aluminum tailhousing? NOW is the time to do something before she's back on the road.

Re: Tranny / tcase problem
With the 4spd long adapter they tend to be weak to start with.
Those builder t-case supports do more damage than without and mixing poly and rubber.

Re: Tranny / tcase problem
What about making some sort of "pinion snubber" type of bumper on the skid plate just to support the overhanging weight of the 205 on that aluminum nv4500 tail housing?

Re: Tranny / tcase problem
How can you tell if your transfer case adapter is cracked? I can't see one but when I come to a stop a hear and feel a clunk under my floor.

Re: Tranny / tcase problem
The thought of driving around and having that happen gives me chills. Another reason to like my divorced case.
