car going to shop for gears!

[chets bird]

well in the morning i am taking my car to the shop to get gears in it!!, these are my options:
i am sending my ocm to texas speed, so the shop will have it for 2 1/2 days,
but i dont have my abs reluctor ring in yet, it was shipped out today and i was told i would have it done by thursday or friday!!, sat is christmas eve!! so should i wait on my abs reluctor ring, or how hard is it to go back and put it in! or should i leave car there till i get the abs ring!! even though that would extend till like next tuesday! through the holidays!! and i dont want that to happen! lmk your opinions
