I bought a used distributor part number td-41u 4m26 for my 1990 honda civic but the pllug-ins were different was it for a 1990 and can I change the ends to make it work

You will likely have major problems. I'd try to sell it and get the proper one. Distributors are the most problematic components on Hondas, in the best of times. It's best to only buy a genuine Honda distributor--most others are junk and not reliable.
