Just to answer the previous questions here, Yes, we have a 1-year warranty that is *nearly* unlimited, basically short of leaving you truck parked on rail road tracks. As the webpage says, "All products guaranteed for one year against defects in materials and labor." And, No, There are no core charges.
Would there be a way to have a Marlin drop-in third built with some treated gears from bobby long if the gears were sent to the shop and there was no hurry?
Yes, this is not a problem at all. When you place the order, just be sure to let us know to expect a package from Longfield (or from you) and we will wait until that package arrives to come in.
Also, what would the reduction in price be to account for supplying the gears?
All you've gotta do is deduct the price of what we sell the gear set individually from the complete drop in third.
For instance, if a 5.29:1 w/Detroit costs $995, and we sell 5.29:1 gears for $195, then $995 - $195 = $800.
