Once and for all- motor mounts??

I have a 87 RCSB 350 TBI/700R4, changing to 5.3/4L60E. As I understand, the 4L60E is the same externaly as the 700/R4. If I want to keep the 4L60E in the same place (to avoid driveshaft work), which motor mounts to use? I understand the DirtyDingo's are adjustable, but do I need them or will the Transdapt 4572 work? I have read the threads, but it doesn't seem clear. Thanks in advance. I wouldn't attempt this if all you guys hadn't plowed this ground before and posted your success.

use the dirty mounts

Thanks, Dirtys on the way.

Be careful ordering from them... It could just be a coincidence but I hadn't used my credit card for almost a year, I bought my motor mounts from DD and suddenly fraud charges all over the place...

Also, you may want to have them powder coat them, or have someone else do it.... After one engine wash....the mounts already show surface rust. They are great for repositioning the motor however....
