    kind of a generic question . your going to have make them according to your motor location.
    I would recomend using some 1/4 plywood and first designing your front mount - then water jet it . Or skill saw carbide blade and patience ! Do the same with your rear plate making sure alignment is exsact with the current location . you can get away with a lil if you have a driveshaft and u joints

    Speaking from experience, I used lightning rail kits before, and have fabbed up my own rails mounts. You would be money ahead buying the pre made kit, with a lot less aggrevation. By the time I aquired all the components, cut, machined, and polished them a kit was cheaper.

    Easier said than done. There really aren't one "generic" template for all BBC's.

    Like Lucky said ... plate sizes will be different depending on how far forward your engine sits compared to the pump, the further forward the taller your plates will be due to the angle of the engine in relation to the hull.

    Easier to get some structural angle aluminum (2"x2") and make your rails, some poster board or cardboard to make templates and make your own plates out of 3/8" thick 6160 aluminum.

    Hope you have a band saw, makes the job a lot easier.

    thanks i have the materails and the tools, just need to be pointed in a direction. i think i have an idea now with your pics, a couple of questions tho.
    Q 1. the way it is set up now with the old stringer mounts i have a 1/4" play (front to back) with the coupler and the pump, should i leave that play in? or have the coupler slid all the way into the pump?

    Q 2. i have 2 by 6 stringers were should i mount the angle at on the stringer, towards the top or should it be down from the top. not sure if this is important question or not.
    again thank you for all your inputs

    1/4" sounds about right as far as the play between the end of the pump shaft and the dl. As far as angle....you want to match the angle on the pump shaft, not so much worry about the stringers.

    Correct on the play

    We put the rails on the stringers level to the top of the stringers, the front plate it taller than the rear giving it the proper angle to align with the pump.

    My rails are at the bottom of my stringers to line things up. But there's no reason the plates couldn't be adjusted to set the rails where ever you want right?

    If you have the tools, definitely do it yourself. Get some transfer punches and locate the holes that way into a piece of 3/8 6061 Aluminum. When you make it yourself you can cut the plates to shape and have a true custom job that was built for your boat. If you are in the socal area and need any help, let me know. I have a block set up for alignment with the pump shaft that will make the job a breeze.
