help with61 apache insturment cluster swap

[arcticman]

Hello, Im looking information on chaning out my inst. cluster. I purchased a insturment cluster out of a larger truck 1.5 0r 2.0 ton 60-63 it has a tac and actual guages. my original cluster has idoit lights. Im not sure if the cluster im installing had a v8 or I6. My truck has the 235 in it. Ive read that I can install a Tac-adapt to correct the tac if its off has anyone used this product? also will I need to change out all my oil and temp sending units ? Is the wiring somewhat plug and play or will that need changing? Thanks for your help.
