    Go hydro if you can find the parts. You'll need the pedal bucket, pedals and rod from clutch pedal to master as well as the clutch master, slave and hydro bell. You can find all this on an '85 or newer pickup or K5.

    I don't blame you. I've had a hell of a time finding hydro clutch parts. I have everything now except for the rod that goes from the clutch pedal to the clutch master.

    yeha, just got deposit for my th350 combo, already got it almost all out, just need a hoist to lower it down.. then yank engine..

    its gunna be 350hp... 488. 465 205, 39.5 boggers, 1 ton of course, high steer, for spring.. also tube sliders, bumpers, tarnny skid/xmember( like yours rene) and internal cage..

    should I rebuild the 465 and toss a centerforce at it, i know the seller very wella nd he says its in tight shape.. but he would put a clutch in it.. should i go center force, pros cons

    also what about a rebuild kit off ebay, 150 us with shipping included it looks like, something to think about..

    Im so happy i could finally start building the beast stage 2

    Go with a Luk Pro-gold clutch. Berts Automotive on King George highway carries Luk clutches. I found this out after my Hays clutch showed up. For the sake of your left leg make sure it's a diaphram clutch and not the three finger (Borg & Beck)

    As long as the tranny didn't have a history of popping out of third I'd just leave it alone.

    I'd change the gear lube and run it. Make sure you don't let your hand rest on the shifter when you're driving it...this is a direct cause of thrid gear pop-out as the pressure you put on the shifter by resting your hand on it wears the shift fork pads out. Easily as bad a habit as riding the clutch.

    well picked up the trans/tacse tonight, goes into reverse real easy.. feels great

    i need a clutch, and i also need to geta broken bolt off in the adapter for the crossmember.. hopefully some lube and a hammer and vice grips get it out, if anything ill weld something on and twist it out, or dril and tap it, etc

    but ive got everything I need for the swap, minus clutch and lubes, looks like a few fresh gaskets on the setup too

    250 cdn and i even got the driveshafts

    Go over that adaptor with a fine tooth comb, as they are pretty famous for cracking...

    Here's another vote for LUK, pro gold is good but a regular old rep set would work just fine. Dial-a-clutch has pretty good prices too, ordered from them a few years ago.

    adapter looks great, took them alla part yesterday, today got the oven cleaner and started the battle on cleaning and painting them

    looks as though they both have newer bearings and seals

    rene, where should i go for the tcase to adpater and tranny to adpater gaskits?

    also what gear lube is best for the stuff we do, truck is weekend toy to trails only

    well ebay looks best bet for gaskets, lordco wanted 75 for just the tcase... can get both trans and tcase kits for under that on ebay.. just gaskets no bearings
